This suggests that either your current directory does not contain R and you have not added the directory containing R to the PATH environment variable in Windows. For that command to work, Windows needs to know where to find the program to execute. You might find this site useful for becoming more familiar with the Windows command prompt (geared towards XP, but cmd.exe has changed little from XP to Vista, to 7---though increasing MS is encouraging users to switch over to using the Windows powershell): http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/ntcmds.mspx?mfr=true > > Can somebody please guide me what to do in this situation? You should also read the official R manual on installing and building R from source. Particularly pay attention to the sections for Windows users. You may want to get Rtools and certainly follow the instructions to add all the necessary directories to your PATH variable. The steps will be something like: Right click My Computer -> Click Properties -> Click Advanced -> Click Environment Variables -> edit the variable "PATH" to include relevant R directories. Please note that this is not an exact step-by-step process as it varies slightly by different versions of Windows.
