Hello,
Perhaps the problem could be related with the CRS setting you are using.
Instead of:
global.map.proj - CRS('+proj=latlon +ellps=WGS84')
you should try:
global.map.proj - CRS('+proj=longlat +ellps=WGS84')
Besides, following your code I think you are not setting the CRS of your

True, but since it was also global data, brick(...) did the right
thing. I have now set its CRS just to be sure.

Use package=ncdf4, not package=ncdf: the latter is no longer supported,
per the developer (of both packages).

switches the parts of wrld_simpl from 0 longitude to the east

Prajjwal,
You can also read these files using ncdf with the the 32-bit version of R
(on windows 64).

Gustaf, Thanks, I think I found the bug. It happens when there is no
overlap at all between polygons and raster. I think it is fixed in raster

Yes I was able to read the file using ncdf. However, I am not able to load
the entire variable in R-32bit using get.var.ncdf command. I get the error
cannot allocate vector of size 2.5 Gb. Also, would this be a problem down
the road if I am working with large datasets in R-32bit?
Thanks,
Prajjwal, You could use 32bit R and the raster package to write the data to
new files; and then continue with 64bit R. Robert

Today I received some ASCII files that need to be converted to raster. They are
organized in a rather odd way, and I cannot think of a method
to read and organize the data to make a raster. Please take a look at a sample

Robert, from what I understand, use raster package in 32-bit to open and
write as a new netCDF file (using writeRaster) and then open in 64-bit using
ncdf. This way I should be able to bypass size limit issue if I come across
large datasets.
So far, I have read the netCDF file as raster using

Is there interest in something like this code for generating SpatialLines?
I use a variation of this fairly regularly:

coords.2 - coordinates(coords.2)
