Start by looking at
?getwd
?read.table
intall.packages('foreign') # if not installed
?read.spss
?read.ssd
etc.

[R] New to R
Hey, I am very new to R and I need to use it (and the ACEPACK package) to do some statistical analysis. I have installed acepack but efforts to get started has been unsuccessful. I can't seem to be able to load my data files because I am yet to figure the syntax to use. Is there a work directory in R where I can put my files and call them anytime, like in Matlab? My files are on my C drive and I just can't figure the syntax to get them into R. Any help?

Re: [R] New to R

[R] new to R: don't understand errors
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 that I don't quite understand. So I'm hoping some of you out there might recognize my issues and be able to point me in the right direction to resolve them. Currently, I have a corpus of ~12,000 text files. I've separated them out into other folder of varying sizes to check if there is some sort of limit on the number of files. Even when I only use the same number as previous working collections, I still get the errors. So I am wondering if it might be something in the files themselves... At any rate I routinely get these two errors. The first is generated when I include a minDocFreq=x, and it looks a little like this when I run it: data(stopwords_en) CCauto = textmatrix( CultureMineTXT , minWordLength=3, minDocFreq=50, stopwords=stopwords_en) Error in data.frame(docs = basename(file), terms = names(tab), Freq = tab, : arguments imply differing number of rows: 1, 0 If I remove the minDocFreq, I get a different error: data(stopwords_en) CCauto = textmatrix( CultureMineTXT , minWordLength=3, stopwords=stopwords_en) Error in as.vector(x, mode) : invalid argument 'mode' Any help would be greatly appreciated.

Hi Linda Did you already get a reply to your question? If not, try adding a new line at the end of the text (just hit enter after 69,the last number in your data and save the file). You also want to use the argument sep in read.table Since you have a comma at the end of each row you can either manually delete that and use read.table, or just import it the way it is and then delete the last variable (V4) created because of the extra comma i.e z- read.table(q.txt, sep=,) z V1 V2 V3 V4 1 1 2 3 NA 2 33 44 88 NA 3 23 43 69 NA #V4 is an artifact from your extra comma at the end of each row newz-z[,-4] #Deletes V4 I hope this helps Francisco From: linda.s [EMAIL PROTECTED] To: R-help@stat.math.ethz.ch Subject: [R] new to R Date: Thu, 23 Mar 2006 01:05:21 -0800 z - read.table(c:/temp/q.txt) Warning message: incomplete final line found by readTableHeader on 'c:/temp/q.txt' what does that mean? my q.txt is like: 1, 2, 3, 33, 44, 88, 23, 43, 69, __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
