It seems to me that the tilde in the path is probably creating some problem in the line command. Probably you can solve the problem installing R in C:/ to avoid the tilde in the path. However, could please open again oneChannelGUI and, in the main R windows, write the following code: affylmGUIenvironment$aptDir affylmGUIenvironment$libDirLocation sessionInfo() You can find me tomorrow morning on skype raffaele.calogero and we can fix the problem.
