Howdy Gurus I 'd like to ask a question about how to build TermDocMatrix in tm text mining package. 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, -- Kum-Hoe Hwang, Ph.D.

Hello, I have been using the TM package to create a TermDocMatrix, which I have saved as a matrix so that I can view word frequencies. Below is a section of the code that I have used and an excerpt of the output: What I wanted to be able to do is to view the output alphabetically - rather than the results being sorted by frequency as below, that an alphabetical list would be generated.

I'm hoping to work with the tm package with some html documents. In the documentation and in the the tutorial material it says that there is a readHTML routine that can be used to read HTML documents into a corpus. However, when I try to use that routine I get an error. When I run getReaders (below) readHTML isn't listed. > getReaders() [1] "readDOC"

The following code is derived from a paper titled "Text Mining Infrastructure in R" (http://www.jstatsoft.org/v25/i05/paper). The example below seems to load some default documents for analysis, some sort of latin document. I cannot for the life of me figure out to load my own document let alone an entire corpus. I have searched the above documenet as well as related documentation.

Hi, I am a new user of R 2.8.1. I use Tinn-R for code editing. I use a windows 2003 system with 1 GB RAM. I am interested to generate dashboard and reports based on data from MS Access. These reports need to be posted on a weekly basis to the web. The reporting interface should provide facilities for "what if" scenarios. Is it possible to interface R analysis results to good open

I'm working on a small project to extract high-frequency terms from a document and then display those terms in web page. To this end, I've to pass the file name as parameter to the Corpus function to build a corpus of only one document. I can build the corpus using the code below interactively in R. But calling the function with a file name as the parameter I got the error message saying

Hi, I bumped into a serious issue while trying to analyse some texts in Bulgarian language (with the tm package). I import a tab-separated csv file, which holds a total of 22 variables, most of which are text cells (not factors), using the read.delim function: data<-read.delim("bigcompanies_ascii.csv", header=TRUE, quote="'",
