r script returns text values and not attachments in dataset



I have just started working with Rscript. I am trying to filter columns based on pattern matching using regex in R-Script.


# 'dataset' holds the input data for this script
dataset$StrDate<- as.character(dataset$Subject)


pattern <- "^[[:alpha:]]{4}\\s\\d{2}\\.\\d{2}\\.\\d{2}"
isMatch <- function(x) {grepl(pattern, as.character(x),}




My input table contains columns such as Subject, Attachments,Body,Sender etc. The attachment column has tables containing pdf attachments. However, the output from the above code is a Name, Value table. After I expand the values column I get all the columns in text format. I need the pdf attachments in Attachments column. Can someone please help with this issue.

Hi @Anonymous,

Re: r script returns text values and not attachments in dataset

Thanks for your response!


I am extracting my inbox email data here from Microsoft exchange online. I cant send across the dataset due to company policy but I am attaching snapshot of all the columns.Capture.PNGCapture1.PNG


Since I want all the emails in the inbox from Cash team I am trying to filter out all the RE: and Fw: here using Rscript. After I filter the emails R-script returns me the following table.




On expanding the values column I see that my input table column values have been converted to string format. Since in the next steps I want to extract the pdf attachment in table under Attachments column, i am not able to do so anymore.


I hope the problem and solution expected is clear.
