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.

Hi,
I am getting error(as below) when trying to write seasonal ( quarterly)
data in netCDF.
My data details and sample data are below.
My code is

library(raster)
library(ncdf)
writeRaster(ncdata.qtr,
filename="QtrYTmax.nc",inf.rm=TRUE,na.rm=T,NaN.rm=T,format="CDF",overwrite=TRUE,verbose=T)

but his gives me the error

*Error in dim.create.ncdf(nc, d, verbose) : *
*  NA/NaN/Inf in foreign function call (arg 5)*

how to fix this error ?
