How to open grib file in R?

but I got this error:
C:\Users\aalyaari\Desktop\Vol_025_H14_2010060700.grib has GDAL driver GRIB
and has 721 rows and 1440 columns Error in validityMethod(as(object,
superClass)) :
  Geographical CRS given to non-conformant data: -90.125  90.125

Any idea why I am getting this error?

At a guess, and this is just a guess, I'd say the system tried to
give a Geographical CRS to non-conformant data...

 So, what's a Geographical CRS? One with latitude and longitude.
What's "non-conformant data"? Data that can't conform to latitude and
longitude. Why is -90.125 not conformable to latitude-longitude?
Because it's further south than the south pole.

 Why have you got data that goes further south than the south pole and
further north than the north pole? I don't know. I suspect you have
points at the poles and the software thinks these are grid cells that
are 0.250 lat-long degrees wide. Ask your source.

For what its worth, the raster package will ignore the error, but
reveals another:

  > g=raster("Vol_025_H14_2010060700.grib")

I suspect there's an off-by-one error in the code that created this.
Remember there are only three possible mistakes in computing - off by
one errors and divide by zero errors.
