[Rnomads-user] Problems with MacOS

[Bowman, Daniel]

Hi Patrick,


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.


What does system("pwd", intern=TRUE) give you?


Keep me posted!

Danny

Hello Danny,

Thank you very much for your nomads work.  I have used it to extract GFS data and plot cross-sections using RAOB. I enjoy looking at your balloon work.  I was the forecaster for a research project studying stratospheric ozone based in Saskatchewan in 1975 and the pictures bring back memories of the ballon launches. We even had some go astray too.

I am migrating from a dual Linux/Windows system to a Macintosh and I cannot get rNomads to work.  The problem seems to be in accessing wgrib2.

Here is a snippet from my bash terminal:

~/SCI/rNomads $ echo $PATH

/Users/pking/ ...   n:/usr/local/wgrib2:/usr/local/wgrib

~/SCI/rNomads $ wgrib2 fcst.grb

1:0:d=2015120900:TMP:800 mb:6 hour fcst:

2:131801:d=2015120900:RH:800 mb:6 hour fcst:

3:378897:d=2015120900:TMP:2 m above ground:6 hour fcst:

4:627907:d=2015120900:RH:2 m above ground:6 hour fcst:

~/SCI/rNomads $

So wgrib2 is on my path and it does find 'fcst.grb' downloaded by rNomads.  However rNomads can't find wgrib2 from within R:

[Workspace loaded from ~/SCI/rnomads/.RData]

> system("wgrib2")
sh: wgrib2: command not found
>

DO you have any idea where I should look now?

Thanks

Pat

Hello all,


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.


Let me know if you have any questions or suggestions for further work.


Best,

Danny
