[Gretl-users] non-interactive R mode does not work but interactive mode does

Hi everyone, I have the following problem. If I create a New R Script in Gretl, I'm able to run it using the Interactive Mode, this is, R GUI opens successfully and does the intended computation. But when try to run the same script using the non-interactive mode, it pops an error message saying: "the system can't find the specified path". Considerations: 1) I'm running Gretl 1.9.1 and R 2.11.1 under Windows XP (but I had the same problem on Windows Vista at home). This is the first time I've tried Gretl, thus never had case where it worked, to compare. 2) This is the script I tried: a <- 4 a 3) I checked the Tools -> Preferences -> General -> Programs and the locations of Rgui.exe (which I guess matters for the interactive mode) and R.dll (ditto for non-interactive mode, right??) both locations are correctly specified. Just in case I clicked on Browse, find each file and double clicked on them and pressed Apply. This may be a well-known problem, but my search on gretl-users list didn´t turned any hits for this issue. thanks in advance, Ricardo
