As question says, I am trying to convert a multi-layer terra raster to a rasterStack object so I can use it with another package (biomod2) that only accepts older raster objects.
Are there any efficient methods of doing this? My only other option seems to save it as a .tif and then re-import it to R using raster.
When I use stack(terraRaster), it duplicated some of the layers. For example, I have a stack that consists of the 19 WorldClim bioclimatic variables plus on layer for geology. Here is was it looks like:
> names(current.clim) # Terra rast object
[1] "bio1" "bio2" "bio3" "bio4" "bio5" "bio6" "bio7" "bio8" "bio9" "bio10" "bio11" "bio12" "bio13"
[14] "bio14" "bio15" "bio16" "bio17" "bio18" "bio19"
> names(stack(current.clim)) # Converted to rasterStack
[1] "bio1" "bio2" "bio3" "bio4" "bio5" "bio6" "bio7" "bio8" "bio9" "bio10" "bio11" "bio12" "bio13"
[14] "bio14" "bio15" "bio16" "bio17" "bio18" "bio19"
> names(stack(c(current.clim, geo))) # Converted to rasterStack with added geology variable
Error in `names<-`(`*tmp*`, value = names(from)) :
incorrect number of layer names

You can use either raster::stack or raster::brick
library(terra)
s = rast(system.file("ex/logo.tif", package="terra"))
library(raster)
sr = stack(s)
# or
br = brick(s)
