...o 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 this, ?readPDF says "Note that this PDF reader needs both the tools pdftotext and pdfinfo installed and accessable on your system." These tools are available from http://www.foolabs.com/xpdf/download.html I am able to download this and use it easily from a d...

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...

...en 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 there something like readPDF() for R? Thanks, Dave Kane PS. If you're curious, here is the sort of work that I want to do with this data: http://www.ephblog.com/2010/01/08/class-update-and-faculty-ages/

...("[app]", "[pdf file]"), wait = FALSE) > system(paste('"C:/Program Files/xpdf/pdftotext.exe"', '"C:/Documents and Settings/tony/Desktop/test/r-intro.pdf"'), wait=FALSE) Method Two - if you want to use the tm package like I did last year, ?readPDF requires the following (not documented anywhere that I know of, but this is what you do): (1) Download xpdf (whichever is the latest version): ftp://ftp.foolabs.com/pub/xpdf/xpdf-3.02pl4-win32.zip (2) Unzip it (3) Download the Redmond utility for adding files to your windows path (free version but...

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 m...

...But calling the function with a file name as the parameter I got the error message saying "Error in eval(expr, envir, enclos) : object 'strFileName' not found" test<-function(strFileName) { src <- URISource(strFileName) cor <- Corpus(src, readerControl = list(reader = readPDF, language = "en_US", load = TRUE)) } After running the following code in R I checked the docURISource$URI and the value is "strFileName" rather than "C:\\Temp\\readme.txt". I also checked the URI when I was debugging the function and the URI is also "strFileName...

...here 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" "readGmane" [3] "readPDF" "readReut21578XML" [5] "readReut21578XMLasPlain" "readPlain" [7] "readRCV1" "readTabular" I'm a missing something? Is there an extra install I'm missing, or has the routine been re...

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. Apreciaríamos su ayuda si nos diesen un script, el paquete pdftable no me resultó.
