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

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")
}

Error ?V
