Migrate spatial predictions from raster to terra #78

Closed jniedballa closed 2 weeks ago

jniedballa commented 4 months ago

Hi Ken, ubms allows spatial predictions using rasters from the raster package. The raster package is no longer being developed though and has been replaced by terra. While raster still works and is on CRAN, it carries the risk of breaking at some point in the future.

Porting spatial predictions in ubms from raster to terra should be straightforward, replacing raster::as.data.frame() in https://github.com/kenkellner/ubms/blob/8c761fda6d69a1377997b18f65dbcc6ff2493ab5/R/predict.R#L64 with terra::as.data.frame(),

and this line: https://github.com/kenkellner/ubms/blob/8c761fda6d69a1377997b18f65dbcc6ff2493ab5/R/predict.R#L68

with out <- terra::rast(out, crs = terra::crs(inp_rast))

nb, I didn't test the code. Thank you and best regards,

Thanks @jniedballa, good idea.
