[Rnomads-user] Problems with MacOS

[Patrick King]

Thanks for your response Danny.

Here is the response to the pwd command:
> system("wgrib2")
sh: wgrib2: command not found
> system("pwd", intern=TRUE)
[1] "/Users/pking/SCI/rNomads"
>

I tried setting the path in both bash_profile and /etc/environment, but R
could not see it in either case.  Apparently Mac OS X does not consult
/etc/environment.  This article (
https://support.enthought.com/hc/en-us/articles/204469160-How-do-I-set-PYTHONPATH-and-other-environment-variables-for-Canopy-)
suggests a way of doing it.  I will try to figure that out and report later.
