Hi:
We are having some very strange problems with R on WIndows, both with
R 2.4.1 and R 2.5.0. The following command:
> download.file(url="http://oceanwatch.pfeg.noaa.gov:8081/thredds/wcs/
> satellite/AG/ssta/14day?
>
request=GetCoverage&version=1.0.0&service=WCS&format=NetCDF3&coverage=
>
AGssta&Vertical=.0&time=2006-01-06T00:00:00Z&bbox=220,20,250,50",
> destfile="junk.nc")
>
on my Mac downloads a netcdf file, which I can open just fine using
the ncdf package, and displays just fine using the netcdf utility
"ncdump -h"
The same command under Windows downloads a file with that name and
with the correct size. A cmp on the two files says there are
differences, and using a hex editor confirms this. The file produces
a simple error when using "open.ncdf" and in fact the ncdump utility
produces:
rmendels% /sw/bin/ncdump -h junk1.nc
/sw/bin/ncdump: junk1.nc: Invalid argument
There is clearly something corrupted in the Wndows version, and yet
it works perfectly on my Mac. I have produced this error on two
different Windows machines with two different versions of R.
Any help appreciated
-Roy M.
