[R] .Call works in R 2 not in R 3

cutree is a function available in stats.
So it might be worth a try to just replace
.Call("R_cutree", tree$merge, k, PACKAGE = "stats”)
and see what happens.
checking the source of cutree shows the following call
ans <- .Call(C_cutree, tree$merge, k)
so replacing R_cutree by C_cutree also might be an option.
But, of course as Uwe recommended,
using a plain R call and not using .Call is the preferred solution.
