[R-sig-Geo] writeRaster error [Error in dim.create.ncdf(nc, d, verbose) : NA/NaN/Inf in foreign function call (arg 5)]

[Robert J. Hijmans]

Aseem provided me with some more info. writeRaster fails when the
'z-value' cannot be converted to an integer. In his case:

> head(getZ(ncdata.qtr))
[1] "1950 Q1" "1950 Q2" "1950 Q3" "1950 Q4" "1951 Q1" "1951 Q2"

The work around is to change these values using the setZ function.
This has been fixed (with a warning) for the next version of the raster package.

Robert

PS. always show sessionInfo(), traceback() and do not include very
large amounts of data in your postings!
