similar to: FW: 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

Hey alltogether, refacturing a package (before it will be released), I ran across the following problem. I have two directories with different text files, I want to read the first and construct a document-term matrix from it (every term=word in a row, every file in a column, occurrence frequencies form the values). The second directory contains different files. It needs to be read in to also

Hello, as I just spent a (too long) while searching for a way how to persistantly switch back the help display routines from chm to text, here a small documentation how to do that with the windows version of R. The windows installer asks which help type you want to use, I wanted to test the chm version -- which I didn't like. If you after installation want to switch back, you have to edit

Dear R team, The following piece of code (to use the lsa package) works fine on my mac os x, but when I run the same code on Windows XP, it doesn't work any more. ### code: library("lsa") matrix1 = textmatrix("C:\\Documents and Settings\\tine stalmans.TINE. 000\\LSA\\cuentos\\", stemming=TRUE, language="spanish", minWordLength=2, minDocFreq=1,

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 "ERROR: cannot allocate vector size of xxx

I have a problem with the textmatrix() function of the LSA package whenever I specify 'removeNumbers=TRUE'. The data for the function are stored in a directory LSAwork which consists of a series of files that houses the text in column form. As long as removeNumbers = FALSE or it is not present the textmatrix function works just fine. The error message I get seems to suggest it is

In case someone else runs into this, I found the problem, it was related to having some zero-length text files. Make sure you have valid (non-empty) data files for loading into the document-term matrix.

Hello, I'm trying to use the "lsa" (latent semantic analysis) package, and running into a problem that seems to be related to the number of documents being processed. Here's the code I'm running (after loading the lsa and rstem packages), and the error message: > SnippetsPath <- "c:\\OED\\AuditExplain\\" # path where to find text snippets >

I am using 'tm' package for text mining and facing an issue with finding the frequently occuring terms. From the definition it appears that findFreqTerms and minDocFreq are equivalent commands and both tries to identify the documents with terms appearing more than a specified threshold. However, I am getting drastically different results with both. I have given the results from both the

Hi, I just noticed that by inspecting the matrix term that no all stopwords are removed, does someone know how to fix that? library(tm) data("crude") d<-tm_map(crude, removeWords, stopwords(language='english')) dt<-DocumentTermMatrix(d,control=list(minWordLength=3, minDocFreq=2)) inspect( dt) I am using R version 2.10, tm package 0.5-3 cheers Welma [[alternative HTML

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 at least two dimensions* This error

Hi all, I am trying to do some text mining with twitter and I am getting the error: Error in structure(names(sapply(possibleCompletions, "[", 1)), names = x) : 'names' attribute [1] must be the same length as the vector [0] When I use tm_map. Has anyone had/seen this error before? The code I have is shown below and this error only occurs with #qantas, hashtags like #asx,

Hi list members I have a vector of strings x=c("w","ex","ee") And I want to get a logical vector showing the positions where my search string "e" matches the elements partially, i.e. is at least the left-hand part of the target strings, i.e. I want to get a vector FALSE TRUE TRUE. Any ideas? Thanks Steve Powell proMENTE social research research |

Hi all R users, Can anyone please let me know how to do the moving average with R? With regards, Abu _________________________________________________________________ Free games, great prizes - get gaming at Gamesbox.
