[R-pkg-devel] Error: [writeRaster] cannot write file

[Keshav, Krishna]

Outdir is either a directory like getwd(), tempdir() etc or empty/null. If it is empty/null, then I set it to tempdir().

if (is.null(outdir) || length(outdir) == 0) {
    outdir <- tempdir()
}
I am not sure how to debug when running it in Rbuilder. But you can look at results here - https://builder.r-hub.io/status/geohabnet_1.0.0.tar.gz-a2eaa40ccf1d026bbebf5077bfb482d5

What were you using as "outdir"?
