Subject: [R-pkg-devel] Error: [writeRaster] cannot write file
In-Reply-To: <SJ0PR22MB2448CB5ADC64FF3B1C14B977B6CEA@SJ0PR22MB2448.namprd22.prod.outlook.com>
You wrote
# create the plots directory if it does not exist
but then created a directory named outdir/plots/typ_Sys.time.tif
You need to rewrite the code like:
plotsdir <- file.path(outdir, "plots")
fp <- file.path(plotsdir, paste(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(plotsdir)) {
dir.create(plotsdir, recursive = TRUE)
}
