Outdir is either a directory like getwd(), tempdir() etc or empty/null.
If it is empty/null, then I set it to tempdir().
That doesn't answer the question, and the link you provided doesn't
answer it either, as far as I can see. In the test and the vignette
that generated the errors, something specific was passed as outdir. But
what? If it was getwd(), that's bound to fail -- you don't have
permission to write there. tempdir() should have worked, but Berry
pointed out some other things that might be problems.

I am not sure how to debug when running it in Rbuilder. But you can look
at results here -

What were you using as "outdir"?

Hi,
I am developing an R package where I need to save Raster file with .tif
extension to the tempdir(). I am using terra::writeRaster for the same. While
it works through R CMD check in mac, it is failing in R hub builder.
Snippet �V
.saverast <- function(typ, rast, outdir) {
if (is.null(outdir) || length(outdir) == 0) {
outdir <- tempdir()
}
# Save the plot as a raster file
fp <- file.path(outdir, paste("plots", "/",
typ, "_",
stringr::str_replace_all(Sys.time(), "[^a-zA-Z0-9]",

# Create the "plots" directory if it doesn't exist
if (!dir.exists(fp)) {
dir.create(fp, recursive = TRUE)
}
terra::writeRaster(rast, overwrite = TRUE,
filename = fp,
gdal = c("COMPRESS=NONE"))
message(paste("raster created", fp, sep = ": "), "\n")
