[R-sig-Geo] GDALinfo with unrecognized format...

[Michael Sumner]

You can wrap it in a ?try:

f <- "file"
#f <- "utm55.tif"

info <- try(GDALinfo(f), silent = TRUE)

if (inherits(info, "try-error")) {
	## do something else
	stop("no good, file not found: ", f)
	
} else {
	## proceed
	d <- readGDAL(f)
}
