layerCor error

[Nowosad]

layerCor(b, fun = cor) had worked in the past, but does not anymore:

library(terra)
#> terra 1.7.67
b <- rast(system.file("ex/logo.tif", package="terra"))   

# works
layerCor(b, "pearson")
#> $correlation
#>             red     green      blue
#> red   1.0000000 0.9980961 0.9501633
#> green 0.9980961 1.0000000 0.9658011
#> blue  0.9501633 0.9658011 1.0000000
#> 
#> $mean
#>            red    green     blue
#> red        NaN 182.2855 182.2855
#> green 185.3509      NaN 185.3509
#> blue  192.8046 192.8046      NaN

#> blue  7777  7777  NaN

# fails (but worked in the past versions)
layerCor(b, fun = cor)
#> Error: object 'mat' not found

Thanks, the internal version,

layerCor(b, "cor") 

worked but layerCor did not work anymore with custom R functions. It now works again

layerCor(b, cor)
