Hello all, I've been working with R & Fridolin Wild's lsa package a bit over the past few months, but I'm still pretty much a novice. I have a lot of files that I want to use to create a semantic space. When I begin to run the initial textmatrix( ), it runs for about 3-4 hours and eventually gives me an error. It's always "ERRO...

Hello all, I'm brand new to the use of R, and I'm trying to quickly learning the rudiments for a couple of projects here at work. I'm working with the lsa package and trying to generate various semantic spaces. I seem to do well with small collections of clean text files, but now that I am trying to work with larger collections of less than perfection files, I'm getting errors

Hello, I am hoping for some advice regarding how I can install the XML package which I require to run package tm. Normally I would use the install package option, however, I have to install the packages to a laptop running XP. The laptop does not have an internet connection.

Any help on a R package would be helpful. Thank you. Ravi -- View this message
