1. Introduction

The PubChemR package features the essential function get_pug_view, specifically developed to provide access to comprehensive summary reports and additional information not typically found in the primary PubChem Substance, Compound, or BioAssay records. Utilizing the PUG View service, a REST-style web service of PubChem, get_pug_view is primarily utilized for generating detailed summaries for the PubChem database record web pages. It can also function as a standalone programmatic web service.

PUG View is expertly designed to provide complete summary reports on individual PubChem records, offering a different approach compared to the PUG REST service, which delivers smaller bits of information about one or more PubChem records. The get_pug_view function sends requests to the PubChem PUG View API, allowing users to retrieve various types of data for a given identifier, including annotations and QR codes. It supports multiple output formats such as JSON and SVG, making it a versatile tool for users who need comprehensive information from PubChem’s database. This vignette aims to elucidate the structure and usage of the PUG View service, offering illustrative use cases to aid new users in understanding its operation and constructing effective requests.

2. Accessing PUG View with get_pug_view

PUG View offers a versatile approach to access structured information from PubChem’s extensive database. Here’s how to leverage the get_pug_view function in R for accessing various data formats and specific record summaries:

2.1. Data Formats

Multiple Formats: PUG View supports various formats. For example, to retrieve JSON data:

result <- get_pug_view(annotation = "data", identifier = "1234", domain = "compound", output = "JSON")

This code initializes a request to retrieve data from the PubChem database for the compound with the identifier “1234” (Gallopamil). The annotation parameter is set to “data” indicating that we want the compound data.

result
#> 
#>  PUG View Data from PubChem Database 
#> 
#>  Request Details:  
#>   - Domain: Compound
#>   - Annotation: data
#>   - Identifier: 1234
#> 
#>  Pug View Details: 
#>   - RecordType (1): [<unnamed character>] 
#>   - RecordNumber (1): [<unnamed numeric>] 
#>   - RecordTitle (1): [<unnamed character>] 
#>   - Section (14): [<unnamed list>] Structures, Names and Identifiers, ... and 12 more.
#>   - Reference (47): [<unnamed list>] 
#> 
#>  NOTE: Run getter function 'retrieve()' with element name above to extract data from corresponding list. 
#>        See ?retrieve for details.

The response provides an overview of the PUG View data for the requested compound, including the domain, annotation, identifier, and available sections. The retrieve() function can be used to extract data from specific sections.

To retrieve the record type:

retrieve(object = result, .slot = "RecordType",  .to.data.frame = FALSE)
#> [1] "CID"

This code extracts the record type, which is “CID” (Compound Identifier).

To retrieve the record number:

retrieve(object = result, .slot = "RecordNumber",  .to.data.frame = FALSE)
#> [1] 1234

This code extracts the record number, which is “1234”.

To retrieve the record title:

retrieve(object = result, .slot = "RecordTitle",  .to.data.frame = FALSE)
#> [1] "Gallopamil"

This code extracts the record title, which is “Gallopamil”.

To retrieve sections of the data:

section <- retrieve(object = result, .slot = "Section",  .to.data.frame = FALSE)
section
#> 
#>  PUG View Data Sections 
#> 
#>  Request Details: 
#>   - Record Type: CID
#>   - Record Number: 1234
#>   - Record Title: Gallopamil
#> 
#>  Section Details: 
#>   - Number of available sections: 14
#>   - Section headings: Structures, Names and Identifiers, ... and 12 more.
#> 
#>  NOTE: Run getter function 'section()' to extract section data. To list available sections, run 'sectionList()'. 
#>        See ?section and ?sectionList for details.

This code retrieves the sections of the data available for the compound. It provides an overview of the number of sections and their headings.

To list the available sections:

sectionList(section)
#> # A tibble: 14 × 2
#>    SectionID Headings                         
#>    <chr>     <chr>                            
#>  1 S1        Structures                       
#>  2 S2        Names and Identifiers            
#>  3 S3        Chemical and Physical Properties 
#>  4 S4        Spectral Information

These detailed interpretations illustrate how to access different types of records, view sub-sections, and extract specific information from PubChem using PUG REST. This approach is applicable for compounds, substances, BioAssays, genes, and other record types supported by PubChem.

2.4. Annotations

Access by Heading: Retrieve specific types of information across PubChem’s databases. For example, to get all experimental viscosity measurements:

result <- get_pug_view(annotation = "annotations", identifier = "Viscosity", domain = "heading", output = "JSON")

This code requests all annotations related to viscosity from the PubChem database. The output format specified is JSON. The resulting object, result, contains the following details:

result
#> 
#>  PUG View Data from PubChem Database 
#> 
#>  Request Details:  
#>   - Domain: DomainSpecific (heading)
#>   - Annotation: annotations
#>   - Identifier: Viscosity
#> 
#>  Pug View Details: 
#>   - Annotation (810): [<unnamed list>] 
#>   - Page (1): [<unnamed numeric>] 
#>   - TotalPages (1): [<unnamed numeric>] 
#> 
#>  NOTE: Run getter function 'retrieve()' with element name above to extract data from corresponding list. 
#>        See ?retrieve for details.

To extract the annotations:

annotations <- retrieve(object = result, .slot = "Annotation", .to.data.frame = FALSE)

The code returns the first few viscosity annotations. The following is an example of what the extracted annotations might look like:

The output shows detailed information for each annotation entry, including the source, name, description, reference, and values.

Or equivalently, we can employ the following if the heading contains special characters not compatible with URL syntax:

result <- get_pug_view(annotation = "annotations", identifier = NULL, domain = "heading", output = "JSON", heading = "Viscosity")
result
#> 
#>  PUG View Data from PubChem Database 
#> 
#>  Request Details:  
#>   - Domain: DomainSpecific (heading)
#>   - Annotation: annotations
#>   - Identifier: 
#> 
#>  Pug View Details: 
#>   - Annotation (810): [<unnamed list>] 
#>   - Page (1): [<unnamed numeric>] 
#>   - TotalPages (1): [<unnamed numeric>] 
#> 
#>  NOTE: Run getter function 'retrieve()' with element name above to extract data from corresponding list. 
#>        See ?retrieve for details.

Specify Heading Type: For headings referring to different record types, specify the heading type. For example, boiling point for compounds:

result <- get_pug_view(annotation = "annotations", identifier = "Boiling Point", domain = "heading", output = "JSON", headingType = "Compound")

This code retrieves all annotations related to the boiling point of compounds. The resulting object, result, contains detailed data:

result
#> 
#>  PUG View Data from PubChem Database 
#> 
#>  Request Details:  
#>   - Domain: DomainSpecific (heading)
#>   - Annotation: annotations
#>   - Identifier: Boiling%20Point
#>

#>   - Annotation (1000): [<unnamed list>]

#> 
#>  NOTE: Run getter function 'retrieve()' with element name above to extract data from corresponding list. 
#>        See ?retrieve for details.

To extract the annotations:

annotations <- retrieve(object = result, .slot = "Annotation", .to.data.frame = FALSE)

The output might include annotations like these:

The extracted data will contain detailed boiling point information for the compound, along with references and source details.

These examples illustrate the versatility of the PubChem PUG REST API in retrieving specific annotations, allowing users to access detailed information efficiently and effectively.

Pagination: When accessing data from PubChem, you may encounter situations where the data spans multiple pages. In such cases, you can use the page parameter to navigate through the pages. Here’s how you can access different pages of data using the page parameter.

To access annotations related to CAS on the 10th page, you can use the following code:

result <- get_pug_view(annotation = "annotations", identifier = "CAS", domain = "heading", output = "JSON", page = "10")

This code retrieves the 10th page of annotations related to CAS. The resulting object, result, contains detailed data about the annotations on that page.

#> 
#>  PUG View Data from PubChem Database 
#> 
#>  Request Details:  
#>   - Domain: DomainSpecific (heading)
#>   - Annotation: annotations

#>  Pug View Details: 
#>   - Annotation (1000): [<unnamed list>] 
#>   - Page (1): [<unnamed numeric>] 
#>   - TotalPages (1): [<unnamed numeric>] 
#> 
#>  NOTE: Run getter function 'retrieve()' with element name above to extract data from corresponding list. 
#>        See ?retrieve for details.

To extract the annotations, use the retrieve function:

annotations <- retrieve(object = result, .slot = "Annotation", .to.data.frame = FALSE)

The head(annotations) code will provide a preview of the annotations. The detailed structure of the annotations is shown below:

The extracted data provides detailed information on each annotation, including the source, name, description, and CAS number, along with relevant references and linked records. This approach allows you to efficiently access specific annotations even when dealing with large datasets that span multiple pages.

2.5. Source Categories

Depositors and SIDs: List all depositors for a given compound, categorized by source type.

The following code snippet retrieves detailed annotated data from the PubChem database for the compound with CID “1234”:

result <- get_pug_view(annotation = "categories", identifier = "1234", domain = "compound", output = "JSON")
result
#> 
#>  PUG View Data from PubChem Database 
#> 
#>  Request Details:  
#>   - Domain: Compound
#>   - Annotation: categories
#>   - Identifier: 1234
#> 
#>  Pug View Details: 
#>   - RecordType (1): [<unnamed character>] 
#>   - RecordNumber (1): [<unnamed numeric>] 
#>   - Categories (8): [<unnamed list>] 
#> 
#>  NOTE: Run getter function 'retrieve()' with element name above to extract data from corresponding list. 
#>        See ?retrieve for details.

This code extracts the “Categories” data from the result using the retrieve() function. The extracted data is stored in the categories variable.

categories <- retrieve(object = result, .slot = "Categories", .to.data.frame = FALSE)

The displayed output of head(categories) will show a list of categories, where each category contains:

The name of the category (e.g., “Chemical Vendors”) A link to a PubChem search for substances in this category A list of sources that have deposited data in this category, including: The Substance Identifier (SID) The source’s name and website URL The URL of the source’s page on PubChem The registry ID of the compound The URL to the detailed record of the source The categories the source belongs to

2.6. Neighbors

Similar Compounds: Get a list of compounds with similar structures and associated information:

result <- get_pug_view(annotation = "neighbors", identifier = "1234", domain = "compound", output = "JSON")

This code fetches data related to compounds similar to the compound with CID “1234”. The result is stored in the result variable and contains information about similar compounds. The function parameters specify that we are looking for “neighbors” (compounds with similar structures) in the “compound” domain.
