SpatVector data frame does not support factor types

[ozjimbob]

The attribute table/data.frame of SpatVector objects, very simply, does not appear to support factor type columns - without any error being returned the columns simply remain char type after attempting to set them as factor,.

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f) 
v$NAME_2 <- factor(v$NAME_2)
is.factor(v$NAME_2)
[1] FALSE

print(v)

Thanks, that was one of these pending things that I needed a little push for. I now get

library(terra)
#terra 1.5.50
f <- system.file("ex/lux.shp", package="terra")
v <- vect(f) 
v$NAME_2 <- factor(v$NAME_2)
is.factor(v$NAME_2)
#[1] TRUE
