R help - Mar 2017 - Reading Multiple Files for Text Mining in R Using TM Package?

Hi All ,

I am trying to read few csv files for some text mining assignment.

I have used this command to check the # of files in the working directory:

length(dir(path="D:/Shivi/R Project", all.files = TRUE))
This results to more than 220 approx.

I just need 3 files from these to use for the text mining purpose however
if i use:

docs<- Corpus(DirSource(directory = "D:/Shivi/R Project"))
this reads all the 220+ files

Please suggest how to achieve this feat. Have researched on stack overflow,
where they have used multiple read.csv statements to read multiple files
however do not find that very effective way.

Thank you.

Hi

Hmm, if you need only three files why not copy them to another directory and use
the same command for reading them from that other directory.

You probably could do this from R itself however I am almost sure that doing
this task by OS is far less complicated.

Cheers
Petr

Hi Pikal,

So i understand it correctly you are advising to temporarily change the
working directory using the setwd syntax.

Thanks, Shivi.
