[R] Help with tm assocation analysis and Rgraphviz installation.
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 association value is less than 1, which
obviously is wrong.
Could any export tell me where did I do wrong?
My R-code is:
R>my.path<-'C:\\textfile'
R>library(tm)
R>my.corpus <- Corpus(DirSource(my.path), readerControl = list
(reader=readPlain))
R>tdmO <- TermDocMatrix(my.corpus)
R>tdmO
An object of class “TermDocMatrix”
Slot "Data":
2 x 1426 sparse Matrix of class "dgCMatrix"
[[ suppressing 1426 column names ‘000’, ‘0092’, ‘0093’ ... ]]

Question2:
I can’t load Rgraphviz in R.
I am using windows XP professional, R 2.8.1
I followed the instruction in this link
http://groups.google.com/group/r-help-archive/browse_thread/thread/413605edc81b3422/b7917083646d9cd2?lnk=gst&q=Rgraphviz#b7917083646d9cd2
and
https://stat.ethz.ch/pipermail/bioconductor/2008-June/022838.html
What I did is
1. Close down any R sessions you have open.
2. Download and install Microsoft Visual C++ 2005 SP1 Redistributable
Package:
http://www.microsoft.com/downloads/details.aspx?familyid=200B2FD9-AE1A-4A14-984D-389C36F85647&displaylang=en
2. Download and install the Graphviz 2.16.1 from the archives:
I also tried 2.18.1, and 2.22.2
3. Check your PATH to see how Graphviz was added: graphvis 2.18 and later
versions will automatically add
C:\Program Files\Graphviz2.16\Bin
to Path.
4. open R and download and install Rgraphviz using:
R> source("http://bioconductor.org/biocLite.R"
<http://bioconductor.org/biocLite.R%22>)
R> biocLite("Rgraphviz")
I got no error before the next step:
R>library(Rgraphviz)
I got this error message:
Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared library
'C:/PROGRA~1/R/R-28~1.1/library/Rgraphviz/libs/Rgraphviz.dll':
LoadLibrary failure: The specified module could not be found.
Error : .onLoad failed in 'loadNamespace' for 'Rgraphviz'
Error: package/namespace load failed for 'Rgraphviz'
What else shall I do?
Thank you in advance!

[R] Help with tm assocation analysis and Rgraphviz installation.
For 2nd question: a) This is a question that is supposed to go to the BioC list, because we are talking about a BioC package. b) The following worked for me in January (but we might have new versions of something): 1. Install the current package from the BioC website (strongly assuming you are using R-2.8.1!). 2. Install graphviz-2.20.3.msi as the graphviz binary (versions of recent graphvzi package and graphviz version must much due to the very frequent changes in the graphviz API) 3. add graphviz binariy directory to your PATH environment variable. 4. Restart everything Shoudl work now.
