That seems right, the function is called labels.rpart and seems to be
similar to the S-Fct labels.tree.
The call itself is
pn <- .C("prlab",
lab = character(2 * length(var)),
as.integer(var2), #with 0 denoting a leaf
where (for the data I tried) var is a vector of factor objects, splits
is an nx2 matrix of strings, xlevels is NULL, var2 and temp are
Of course I can send the whole code, if someone is interested.
