Re: [R] [R} how to build TermDocMatrix in tm text mining package of R

2009-01-11 Thread Kum-Hoe Hwang
Thank your comments very much.

Thank to your help, I understood a flow for a text analysis.

However, I could not run the above R scripts because tm package does
not work in my PC that is a critical error.

 Hi there, I think something like the following is what you want:

 ### R start...
 # if you put your plain text files in a folder like this
 my.path - 'C:\\Documents and Settings\\tony\\Desktop\\texts\\'

 # then you can construct a simple tdm like this
 library(tm)
 my.corpus - Corpus(DirSource(my.path), readerControl = list
 (reader=readPlain))
 my.tdm - TermDocMatrix(my.corpus)

 # this show show how words are distributed in the first text document
 my.tdm[1, ]
 ### R end.

 by the way, there are some nice examples of using the tm package in
 the last Rnews letter (Volume 8/2, October 2008), under the section
 'An Introduction to Text Mining in R':

 Hope that helps a little bit,

 It is not clear about importing a plain text file, and them converting that
 text file into TermDocMatrix file, etc to me.
 How can I build a TermDocMatrix of  a plain text document file for text
 association?
 Or are there any good manuals?

 Thank you in advance,
