This tutorial will walk you through the basic usage of the package. ## Installation You can install the `reptiledbr` package from GitHub using: ```r # install.packages("pak") pak::pak("PaulESantos/reptiledbr") ``` ## Basic Usage ### 1. Loading the package Let's start by loading the package: ```{r} library(reptiledbr) ``` ### 2. Retrieving data for specific species The main function of the package is `get_reptiledb_data()`, which allows you to search for one or more species: ```{r} # Create a list of species to search species_list <- c( "Lachesis muta", "Python bivittatus", "Crotalus atrox" ) ``` This function will connect to The Reptile Database, search for each species, and download the available information. During the process, you'll see progress messages like: ```{r} # Get data for these species reptile_data <- get_reptiledb_data(species_list) ``` ### 3. Understanding the returned data The `get_reptiledb_data()` function returns a tibble with columns containing both metadata about the search and the actual data retrieved: ```{r} reptile_data ``` The `data` column contains nested tibbles with all the information scraped from each species page. ### 4. Formatting data with specialized functions `reptiledbr` provides several specialized functions to extract and format specific types of information: #### Synonyms ```{r} format_synonyms(reptile_data) ``` #### Distribution information ```{r} format_distribution(reptile_data) ``` #### Higher taxonomic classifications ```{r} format_higher_taxa(reptile_data) ``` #### Subspecies information ```{r} format_subspecies(reptile_data) ``` #### Common names ```{r} format_common_names(reptile_data) ``` #### Reproduction information ```{r} format_reproduction(reptile_data) ``` #### Type specimens ```{r} format_types(reptile_data) ``` #### Diagnosis information ```{r} format_diagnosis(reptile_data) ``` #### Comments ```{r} format_comments(reptile_data) ``` #### Etymology ```{r} format_etymology(reptile_data) ``` #### References ```{r} format_references(reptile_data) ``` ## Handling Special Cases The package provides proper error handling for various cases: ### 1. Trinomial names (subspecies) If you search for a trinomial name (genus + species + subspecies), the package will issue a warning and skip the search: ```{r} species_list <- c( "Lachesis muta", "Bothrops atrox insularis" # Trinomial name ) reptile_data <- get_reptiledb_data(species_list) ``` ### 2. Incomplete species names The package can also handle incomplete species names, but it will warn you if no data is found: ```{r} species_list <- c( "Lachesis muta", "Lachesis sp" # Incomplete species name ) reptile_data <- get_reptiledb_data(species_list) ``` ## Conclusion `reptiledbr` provides an easy and structured way to access reptile species information from [The Reptile Database](http://www.reptile-database.org/). The package handles many common edge cases and provides specialized functions to extract and format specific types of information. This makes it a valuable tool for herpetologists, ecologists, and other researchers working with reptile data.
