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. > getReaders() [1] "readDOC"

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

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

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

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

Estimados En ocasionas hay informaciones epidemiológicas en reportes pdf semanales como el que adjunto que quisiéramos llevar a csv o txt USANDO R para poder analizarlas estadísticamente.

The following code is derived from a paper titled "Text Mining Infrastructure in R" (http://www.jstatsoft.org/v25/i05/paper). The example below seems to load some default documents for analysis, some sort of latin document. I cannot for the life of me figure out to load my own document let alone an entire corpus. I have searched the above documenet as well as related documentation.

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

Hello everybody, I work, I try, with TM but I have a problem with some special words in french. I think this is due to the manner to transform PDF to text, but I'm not perfectly sure.
