Is R in your $PATH? What do you get if you run (in a terminal) which R?

it is my first time and this problem make me confuse,, how can i add R in my PATH?

i installed windows version of R, while cnv-seq wrote for linux, i use cygwin on windows. this can disrupt my analysis with cnv-seq?i must use cnv-seq on linux?

I understand that you feel comfortable using Windows, but Linux is not as scary as you think. If you plan to do more bioinformatics, it's definitely worth to make the switch (e.g. to Ubuntu). You'll thank yourself later, your work will absolutely benefit from it. Many tools are exclusively for Linux and it's far more convenient for many tasks.

That said, if you want to keep your current setup, my guess would be that you need to install R in cygwin (although I've never used cygwin).
