How to open grib file in R?

Your question should have been posted to the R-sig-geo mailing list.
FWIW I have no direct experience with the files or functions you are using, but I have to say the error message seems pretty clear to me: latitude values are normally limited to [-90,90], but your file appears to have data outside this range. Thus, the file appears to have invalid data.

I have just contacted the sources and I am told that he checked min/max lat/lon for the file and it was right. He is using Linux while I am using Windows, would that be problematic? -- View this message in context: http://r.789695.n4.nabble.com/How-to-open-grib-file-in-R-tp4655497p4655517.html Sent from the R help mailing list archive at Nabble.com.
