Reading PDF files (using xpdf)
Greetings Zaki,
You should really post this question on the R-help forum so that
others might benefit from any responses. It's been a while since I've
done this, but if memory serves, the basic process was to download
xpdf and add it to the windows path, thus making it accessable from
within R. Two methods follow:
Method One (easiest) - using the awesome ?system command:

Reading PDF files
Hi:
I need to do text mining on PDF files. I understand there is a readPDF
command in tm that can be used. Have read the 2008 posts on converting
PDF files to text by Tony Breyal and others.
Wondering if the procedure has been standardized in any tutorial or
otherwise? Being new to R, I was able to follow only part of the
discussion.
Any way to get a set of step by step instructions

parsing pdf files
I have a pdf file that I would like to parse into R:
http://www.williams.edu/Registrar/geninfo/faculty.pdf
For now, I open the file in Acrobat by hand, then save it "as text"
and then use readLines(). That works fine but a) I am concerned that
some information may be lost and b) I may be doing this a lot, so I
would rather have R grab the information from the pdf file directly.
So: is

Figuring out encodings of PDFs in R
Dear list,
I am currently scraping some text data from several PDFs using the
readPDF() function in the tm package. This all works very well and in most
cases the encoding seems to be "latin1" - in some, however, it is not. Is
there a good way in R to check character encodings? I found the functions
is.utf8() and is.local() in the tau package but that obviously only gets me
so far.

Can't pass file name as parameter to Corpus function
I'm working on a small project to extract high-frequency terms from a
document and then display those terms in web page. To this end, I've to pass
the file name as parameter to the Corpus function to build a corpus of only
one document. I can build the corpus using the code below interactively in
R. But calling the function with a file name as the parameter I got the

problem with heatmap.2 in package gplots generating non-finite breaks
I have written a wrapper for heatmap.2 called
heatmap.w.row.and.col.clust which auto-generates breaks using
breaks<-round((c(seq(from=(-20 * stddev), to=(20 * stddev))))/20,
digits = 2) #(stddev in this case = 2.5)
This has always worked well in the past but now I am getting an error
that non-finite breaks are being generated. Drilling down, it seems
that my wrapper is generating finite

help with regular expressions in R
I'm having trouble achieving the results I want using a regular expression.
I want to eliminate all characters that fall within square brackets as well
as the brackets themselves, returning an "". I'm not sure if it's R's use of
double slash escapes or something else that is tripping me up. If I only use
one slash I get

readHTML within tm package
I'm hoping to work with the tm package with some html documents. In the
documentation and in the the tutorial material it says that there is a
readHTML routine that can be used to read HTML documents into a corpus.
However, when I try to use that routine I get an error. When I run
getReaders (below) readHTML isn't listed.

glibc detected *** /usr/lib64/R/bin/exec/R: double free or corruption ???? tm package
Hi,
I have a collection of .txt documents in my working folder for which I want to do some text mining. If I run TextDocCol from the tm package, R crashes with some memory issues. Does anyone has any idea if this is related to R itself or to the tm package?
Below you can find what is happening here.

Still unsure of the Dag Repos for CentOS 3
I have read the Wiki for the Yum stuff, and tried to pay attention to the
variations for Centos 3/Centos 4 mentioned, but for the life of me, I can't
seem to get the Dag repo working properly on my CentOS 3 system. I have
installed the rpmforge rpm, but this doesn't seem to do much. It does
create(I think it created it) the yum.repos.d folder, and I edited the Dag
repos file to be

Bash, mostly, but also ksh and zsh; sorry for not mentioning this. I now see
that the root account usually does not change the behaviour of cd, so we may
as well forget about the matter. My thought was: if a small change helps
avoid this problem (which I think can occur easily enough), it could be

I still don't know what you did to be able to reproduce this (and I did
ask). And as it is a shell script running under /bin/sh, it must be

It turns ou that I was not quite correct regarding the cause of cd printing

[LLVMdev] Hitting assertion, unsure why
I am hitting this assertion:
assert(I != VRBaseMap.end() && "Node emitted out of order - late");
I am not sure why this assertion is being triggered or what I changed
that is causing it.
This is asserting when SDValue is FrameIndexSDNode 1.
I don't have any code that modified frameindices until my overloaded
RegisterInfo function.
I've attached the bc file.
