I'm new to R. I'm working with the text mining package tm. I have several
plain text documents in a directory, and I would like to read all the files
with extension .txt in that directory into a vector, one text document per
vector element. That is, v[1] would be the first document, v[2] the second,
etc.
I know how to read the documents into a tm Corpus, but that's not what I
want to do. I would think that this kind of operation should be elementary
and the first step in any text mining.
Thanks,
Richard
Hi Richard,
Try somthing along these lines:
file_list = list.files("/where/are/the/files")
obj_list = lapply(file_list, FUN = yourfunction)
yourfunction is probably either read.table or some read function from
the tm package. So obj_list will become a list of either data.frame's or
tm objects.
cheers,
Paul
