Hi all, I have a 2 files, one with a series of beginning and end times of animal dives in (lets call it dives). The other file is readings from a time-depth recorder, there is a datetime reading for every second, a temperature and light level reading (lets call it tdr). Now I want to say from the file dives, using the start and end time of the dives, go to the tdr file and find me the

Hi List I have the next code and the error. I have try with other codes and I have the same problem. > reut21578 <- system.file("texts", "crude", package = "tm") > (r <- Corpus(DirSource(reut21578), readerControl = list(reader = > readReut21578XMLasPlain))) A corpus with 20 text documents > (r <- Corpus(DirSource(reut21578), readerControl =

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.

Hi R-Users,   Thanks in advance.   I am using R-2.12.0 on Windows XP.   I am trying to produce an n X m matrix from text data stored in different files. Where n = number of words (say w1, w2, …, wn). M is the number of documents (say d1, d2, …, dm)   A. Using package tm   I am using package tm to do the job. I have provided the code below:   > my.corpus <- Corpus(DirSource(my.path),

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

I have an arbitrary number of spreadsheets that I want to consolidate into a single data frame. The spreadsheets all have the same structure: location, depth1Reading, depth2reading, depth3reading, depth4reading, depth5reading The spreadsheets have their reading date in their file name. This gets parsed out and added to the data frame as a factor. The file name gets recorded in the data

Hello. I am trying to work with the text mining package tm. I have a directory called textsTweet1 which contains three files short.txt myTextFile.txt myTextFile.csv short.txt contains one line: THE CAT IN THE HAT\n myTextFile contains some tweets from Twitter. The first few lines of myTextFile.txt are: @oliviamunn I miss a good Yakaniku...I miss Japan...I NEED COCO EVERYBODY. I NEED TO GET ON

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. This

Howdy Gurus again Thanks to Tony.Breyal, I was able to writing the following script for analyzing a text document. But I got an error with "tm' package. I don't why I got the error from the R script below. I think I followed proccess of R tm manual. I use R v2.8.1. and tm_0.3-3.zip under Win XP. Thanks in advance, Kum Hwang > # setting directory > my.path

Help with tm assocation analysis and Rgraphviz installation. THANK YOU IN ADVANCE Question 1: I saved two txt file in C:\textfile And each txt file contents only one text column, and both have 100 records. I know term “research” occurs 49 times, so I want to find out which other words are correlated to this word, and I got tons of association ‘1’ . I tried other terms, and no

Hi, Gurus Thanks to your good helps, I have managed starting the use of a text mining package so called "tm" in R under the OS of Win XP. However, during running the tm package, I got another mine like memory problem. What is a the best way to solve this memory problem among increasing a physical RAM, or doing other recipes, etc? ############################### ###### my 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. Thanks _____________________________________________ Dr.Ruixin ZHU Shanghai

Hi, I'm very new to working with sparse matrices and would like to know how I can column permute a sparse matrix. Here is a small example: > M1 <- > spMatrix(nrow=5,ncol=6,i=sample(5,15,replace=TRUE),j=sample(6,15,replace=TRUE),x=round_any(rnorm(15,2),0.001)) > M1 5 x 6 sparse Matrix of class "dgTMatrix" [1,] 2.983 . 1.656 5.003 . . [2,] .

Hi, I'm getting crazy: This does work: library(Matrix) a1<-b1<-c(1,2) c1<-rnorm(2) aDgt<-spMatrix(ncol=3,nrow=3,i=a1,j=b1,x=c1) png("myImage.png") image(aDgt) dev.off() But this doesn't !!! f<-function(x){ png("myImage.png") image(x) dev.off() } f(aDgt) My image is saved as a text file and contains nothing at all !!!
