I am using code that previously worked to remove stopwords using package "tm". Even manually adding "the" to the list does not work to remove "the". This package has undergone extensive redevelopment with changes to the function syntax, so perhaps I am just missing something. Please see my simple example, output, and sessionInfo() below. Thanks!

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. Firstly I tried the file - XML_1.99-0.tar.gz . Below is the error I received Error in gzfile(file, "r") :

Dear R-user, Could anybody tell me of the key difference between data mining and text mining? Please make a list for packages about data/text mining. And give me an example of text mining with R (any relating materials will be highly appreciated), because a vignette written by Ingo Feinerer seems too concise for me.

I am using the package "tm" for text-mining of abstracts and would like to use it to find instances of gene names that may contain white space. For instance "gene regulatory protein 1". The default behavior of tm is to parse this into 4 separate words, but I would like to use the class constructor "dictionary" to define phrases such as just mentioned. Is this

I am familiar with packages that read and write Excel files on both Windows and Linux platforms. Do any packages provide similar functionality for MS Word files? I have a lot of text processing to do and the text is embedded in ~200 different Word files (.doc format Office 2003). All I need to do is read, not write.

Hi everybody, I am a new R user. Is there any package devoted to "text mining" analysis in R ? Thanks Gilles lepape.gilles at neuf.fr

Greetings! My ultimate goal is to have fetchmail/getmail poll from POP3/IMAP servers and deliver mail into Dovecot mailboxes. This does not work because the Dovecot LDA for some reason fails. I believe I have narrowed down the problem to dovecot-auth not finding my userdb. But, I am able to connect to dovecot via IMAP in my MUA and preform operations (read, delete mail, create folders).

This allows the straight-forward integration of existing methods for classification, clustering, visualizations, etc. The package is designed in a modular way to enable easy integration of new file formats, parsers, transformations and filter operations.

I have recently started using "tm" package by Feinerer, K. Hornik, and D. Meyer. While trying to create a term-document matrix from a corpus (approxly 440 docs) I get the following error: tdm <- TermDocumentMatrix(tmp, control=list(weighting=weightTfIdf, minDocFreq=2, minWordLength=3)) *Error in rowSums(m > 0) : 'x' must be an array of...

Hi all, I have tried to create a DocumentTermMatrix with a tm package, but i get this error : Error in tolower(txt) : invalid input 'PROD Z LAHKO GNETNO MELJNO GLINO, ... in 'utf8towcs' I tried doing this as it is showed in : http://www.r-project.org/doc/Rnews/Rnews_2008-2.pdf (An Introduction to Text Mining), with this R code :

...finally verified this as follows: 1) Fresh installation of Windows/Java/R. Snowball package works perfectly. 2) Install Quicktime. Java errors produced when attempting to use Snowball package. 3) Uninstall Quicktime. Snowball package works perfectly again. Many thanks to profs Ligges, Hornik, and Feinerer for their kind help in diagnosing this.

hi, has anyone ever tried (hopefully with success ;-) to run icq2000a on wine ? (copied over or installation on wine wouldn't make any difference. i'd like to have this, 'cause i decided to kill my last windows-box. the only app i used there was ICQ. but i don't want to loose all my contacts and history-files. so i'm not going to use any linux-icq-clone (unless i find

Hi Y'all, I am using the text mining package (tm). I am trying to filter out all of the words in a Term Document Matrix that are not in a list of words that I am interested in. I am using the following code: z<-tm_intersect(txt.dtm, c("communications", "safety", "climate", "blood", "surface", "cleanliness",

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="'",
