<p>Hi Patrick,</p>
<p><br>
</p>
<p>Thank you, I'm glad rNOMADS has been useful. First of all, where are you adding wgrib2 to the path variable? If you're using your local bash user profile, it could be that R never calls bash and thus never uses it. In Linux, I always set it in /etc/environment,
so that the variable is set for all users in all environments.</p>
<p><br>
</p>
<p>What does system("pwd", intern=TRUE) give you? <br>
</p>
<p><br>
</p>
<p>Keep me posted!<br>
<br>

<p>Hello all,</p>
<p><br>
</p>
<p>I've just released rNOMADS 2.1.6. It now allows you to define a region to return data from in ReadGrib. This should speed up data processing by orders of magnitude for those of you who are using archived grib data (such as gfs-anl), since those don't give
an option to subset server-side.</p>
<p><br>
</p>
<p>Let me know if you have any questions or suggestions for further work.</p>
<p><br>

<p>Best,</p>
