problem with loop to put data into array with missing data for some files
...data.
The situation so far:
I downloaded 50 years worth of GRIB data files from the NCEP data site
http://nomad3.ncep.noaa.gov/pub/reanalysis-1/month/grb2d.gau/
I then created a loop in R to read each month of each of the 50 years worth of
files and only extract the precipitation records using wgrib and grep as show in
the code at the end of this message. I had to use grep to extract the PRATE
records each time, as unfortunately with these grib files precipitation is not
always the same record number each time.
This worked fine until Feb 1972 (which is file

using grib files in R
I am not new to R, but I am new to .grib files. I am downloading some
climate data and I would like to analyze it in R. R has a nice netcdf
package, but I don?t see any package available to deal specifically
with grib files. I see a few posts from other people using grib files
in R. However, I was unclear if they used grib files in a different
software program and then imported the data
