error in twdtwAssess

[SRKabir]

Hi Victor, I'm having problem with "twdtwAssess". It shows the following error: Error in to - from : non-numeric argument to binary operator In addition: Warning message: In FUN(X[[i]], ...) : Computing the approximate surface area in km2 of cells in an unprojected (longitude/latitude) Raster object. See ?raster::area

here are some info:

@EnvSci can you provide a reproducible example as well as str(r_lucc)?
