Hi
I am new to Cygwin and Linux.
I installed R under Cygwin as part of the setup
I chose "All" during installation, for all packages. So I have the FULL
installlation of cygwin up and running, including gfortran.
*Under Cygwin, how do I check and configure the path to the various
libraries?*
I am trying below command and it says, cannot find "lgfortran"
But I have installed gfortran from "All" and "Libs" during setup
I access R as below
1) R
2) install.pacakges('vegan')
3) After choosing mirror, here is the output I get
* installing *source* package vegan ...
