[R] Parsing "back" to API strcuture

[Eric Fail]

Dear R experts,

I'm reading data from an online database via API and it gets delivered in this messy comma separated structure,

> RAW.API <- structure("id,event_arm,name,dob,pushed_text,pushed_calc,complete\n\"01\",\"event_1_arm_1\",\"John\",\"1979-05-01\",\"\",\"\",2\n\"01\",\"event_2_arm_1\",\"John\",\"2012-09-02\",\"abc\",\"123\",1\n\"01\",\"event_3_arm_1\",\"John\",\"2012-09-10\",\"\",\"\",2\n\"02\",\"event_1_arm_1\",\"Mary\",\"1951-09-10\",\"def\",\"456\",2\n\"02\",\"event_2_arm_1\",\"Mary\",\"1978-09-12\",\"\",\"\",2\n", "`Content-Type`" = structure(c("text/html", "utf-8"), .Names = c("", "charset")))

I have this script that nicely parses it into a data frame,

> (df <- read.table(file = textConnection(RAW.API), header = TRUE, 
sep = ",", na.strings = "", stringsAsFactors = FALSE))
>   id     event_arm name        dob pushed_text pushed_calc complete
> 1  1 event_1_arm_1 John 1979-05-01        <NA>          NA        2
> 2  1 event_2_arm_1 John 2012-09-02         abc         123        1
> 3  1 event_3_arm_1 John 2012-09-10        <NA>          NA        2
> 4  2 event_1_arm_1 Mary 1951-09-10         def         456        2
> 5  2 event_2_arm_1 Mary 1978-09-12        <NA>          NA        2

I then do some calculations and write them to pushed_text and pushed_calc whereafter I need to format the data back to the messy comma separated structure it came in.

I imagine something like this,

> API.back <- `some magic command`(df, ...)

> identical(RAW.API, API.back)
> [1] TRUE

Some command that can format my data from the data frame I made, df, back to the structure that the raw API-object came in, RAW.API.

Any help would be appreciated.

Thanks for reading.
