Thank you for helping. I am running the 32-bit version of R on a 64-bit Windows XP machine. After reinstalling the rJava package I started getting a windows pop up with the message:
Rgui.exe - Unable to Locate Component "This application has failed to start because jvm.dll was not found. Re-installing the application may fix this problem" I have installed the 32-bit version of Java, added the jvm.dll to the Windows PATH environment variable I have also reinstalled R. I still get the error below without any pop-up message: > library(rJava) Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library 'C:/R/R-2.7.2/library/rJava/libs/rJava.dll': LoadLibrary failure: The specified module could not be found. Error : .onLoad failed in 'loadNamespace' for 'rJava' Error: package/namespace load failed for 'rJava' Thanks for the help charis Uwe Ligges-3 wrote: > > Or better ask, is the an 64-bit version of R?
