Dear Gretl Team, I tried to estimate some stuff using R (via Gretl) and I got an error. Look at the command: <hansl> foreign language=R --send-data l_cambio <- gretldata[,"l_cambio"] PP.test(l_cambio,lshort=TRUE) PP.test(l_cambio,lshort=FALSE) end foreign </hansl> Gretl shows me an error message: "C:/Users/henrique/AppData/Roaming/gretl/R.msg: No such file or directory" Looking at ".gretl2rc" file I realized what is going wrong: # Command to launch GNU R Rcommand = C:\Program Files\R\R-2.15.0\bin\R.exe # Path to Rterm.exe Rbin = C:\Program Files\R\R-2.12.2\bin\i386\Rterm.exe # Path to R library Rlib = C:\Program Files\R\R-2.15.0\bin\i386\R.dll The path to Rterm.exe is incorrectly assigned and it can't be changed via the GUI options. To solve my problem I just edited the path to Rterm.exe: Before: "Rbin = C:\Program Files\R\R-2.12.2\bin\i386\Rterm.exe" After: "Rbin = C:\Program Files\R\R-2.15.0\bin\i386\Rterm.exe" I think it would be good to have this option in our GUI menus (once it could be difficult to the unexperienced users to edit the ".gretl2rc" file).
