terra::ext not giving desirable results for raster object

[krishnakeshav]

results are terra::ext() in windows os seems incorrect.

> tf <- paste(tempfile(), ".tif", sep = "")
> utils::download.file("https://geohabnet.s3.us-east-2.amazonaws.com/util-rasters/map_grey_background.tif", destfile = tf, method = "auto")

I am running the above code and using it's result to create raster object -
> terra::ext(terra::rast(tf))
Result in macOS -

SpatExtent : -180, 180, -60, 90 (xmin, xmax, ymin, ymax)

Result in windows -

SpatExtent : 1.2571897007951e+93, 3.54207331254988e+106, -3.98175728485226e+217, 3.87995991987763e+62 (xmin, xmax, ymin, ymax)

The bad result in windows is causing -

> terra::rast(tf)
> terra::crop("some_raster", terra::ext(-115, -75, 5, 32)

[crop] extents do not overlap

MacOS -

packageVersion("terra")
[1] ‘1.7.39’

Win -

> packageVersion("terra")
[1] ‘1.7.39’

I am running latest version of R studio in both OS.

That is a download error. On Windows you should use argument mode="wb"

url <- "https://geohabnet.s3.us-east-2.amazonaws.com/util-rasters/map_grey_background.tif"
tf <- file.path(tempdir(), basename(url))

utils::download.file(url, destfile = tf, mode = "wb")
