...the same version of R 2.11 (but of course windows binary). Usually, there is no problem in doing this and all objects work as expected. I am often doing this to be able to produce wmf or emf graphic files that I need. This time I had some spectra that I have taken the first derivative of with the sav_gol function in the RTisean package. I know RTisean is just an interface to the Tisean executables. The trouble I am facing is that it seems that the location of the Tisean executables is somehow hard coded to the R workspace file. I assume this since when I try to rerun the sav_gol on the windows mac...
