Dear R-Help, I need to convert a set of '.pdf' files into an equivalent set of '.txt' files. This is so that i can do some text mining on the content. In the latest R-News letter (http://cran.r-project.org/doc/Rnews/ Rnews_2008-2.pdf), the package 'tm' for text mining is mentioned. In that lovely package, there is a function called 'readPDF()'. In order to use

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: (1) Download

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

The documents we want to index come in many formats; e.g., HTML, PDF, RTF, Word, Excel, etc., etc., etc. I''ve been searching to find parsers that will translate each of these formats to indexable text, but have had little success. Any help will be appreciated. -- Posted via http://www.ruby-forum.com/.

Dear All,   I need to create eps file which is the required figure format  of the journal that I want to submit a paper. I am able to create files in pdf or wmf format but not in eps format.

All, Thank you for the prompt and useful answers to my questions. I had missed references in 5.7.6 which would have answered some of the points. As Bill pointed out a newer version of acrobat would help, but the Sun system here is still running 5.0. (An oversubscribed sysadmin). Then I could have searched and at at least avoided the most trivial. All three comments were different,

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

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.

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 error message saying

I had, in the past, a .pdf reader that also permitted me to fill in some information, when I received a .pdf file. I have KPDF installed, but that seems to only have Reader capability.

Hello, Recently, the following problem started happening with a particular samba server: If i have a file open for reading (say, a pdf in xpdf) and then try to write to it (say, through recompiling a latex document) it complains that it cannot open the file for writing. this seems like a file lock issue but I am unsure where it is happening. My previous usage should be perfectly safe since
