Hello,
I am trying to use the "tree" package in R with RSperl.
I have generated a regression tree using the "tree" package in R and saved it
in a file say "RegTree_2.Rdata"
If I use the predict function from R command line, it works fine. However, I
want to use it from within perl using RSperl. To do that, here is what I do,
my $regTree = "RegTree_2.Rdata";
my $tree = &R::load($regTree);
my $ans = &R::call("predict.tree", $tree, $_[0]);
On running my code, I get the following error:
Error in predict.tree("rtree_2", list("5031601", "GS0098", 0, "1", "1", :
not legitimate tree
Any help would be appreciated.
Thanks
-Rachana
