Error installing PDE on Spanish version of Windows

[evgc01]

Hi,

I tried to install PDE on R for windows (spanish version) but when I ran the command "PDE_install_Xpdftools4.02()" I got the following strange error:

Error in system(paste0(""", pdftotext_location[i], "" "", "-layout", :
'"INFORMACI�N: no se pudo encontrar ning�n archivo para los patrones dados."' not found

INFORMACIÓN: no se pudo encontrar ningún archivo para los patrones dados"

Browsing across the source code of "PDE_install_Xpdftools4.02()", I found it first calls "PDE_check_Xpdf_install()".

And in turn PDE_check_Xpdf_install() executes this line of code several times:

    if (sysname == "Windows") {
        pdftotext_location <- suppressWarnings(system("C:\\WINDOWS\\system32\\cmd.exe /c where pdftotext", 
            intern = TRUE))
        if ("INFO: Could not find files for the given pattern(s)." %in% 
            pdftotext_location)

"INFO: Could not find files for the given pattern(s)" is the response "where" command returns when a file is not found but just in the english version of windows.
In the spanish one the response is "INFORMACIÓN: no se pudo encontrar ningún archivo para los patrones dados" which is the spanish translation, and because of encodings, the non english charactes appears distorted. It happens the system is windows, but obviouly is not a valid location, so an error is thrown.

Is there any workaround?

Best regards.

Hi,
Thank you for letting me know about the issue. I will post an updated version on github and CRAN by tomorrow evening. In the meantime, if you installed the github version of the package you use the following fix:

1. Locate the PDE package location with:
   system.file(package = "PDE")
2. Open the bin subdirectory and create a file called XPDF_DIR.config with a text editor in the subdirectory.
3. Enter 3 lines into the file with a text editor:
   <PDE_package_dir>\bin\xpdf-tools-win-4.02\bin64\pdftotext.exe <PDE_package_dir>\bin\xpdf-tools-win-4.02\bin64\pdftohtml.exe <PDE_package_dir>\bin\xpdf-tools-win-4.02\bin64\pdftopng.exe
   replacing <PDE_package_dir> with the filepath from the system.file(package = "PDE") command.

That should fix the problem and get rid of the requirement to run PDE_install_Xpdftools4.02().

Best
Erik
