Dear all, Does the package ?hier.part? limited to only 12 predictor variables. I was trying to use it to partition (select) the most relevant predictor variables our of 30 ones, and I always get an error message says: ?Error: Number of variables must be < 13 for current implementation? Thanks in advance for your assistance.
