R terra package warp function missing

Question

I want to use warp function from terra package, but it seems the function is not available in my terra library. Is this a bug? Or could it relate to system gdal installation? I have not installed gdal outside R.

Edit: After more workaround I guess function terra::warp was in newer version renamed to terra::resample . So, there is maybe just inconsistency in help.

Answer 1

Instead of a single warp method, terra has resample and project . With resample primarily to transform raster data to another resolution. This is for cases where this cannot be done with (dis)-aggregate --- which would otherwise be preferred. And with project primarily for transforming the data to another coordinate reference system.
