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

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]", ""),
".tif", sep = ""))
# 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")
}
