Minor Release

NEW FEATURES

• ordinate function.
• summary.ordinate and plot.ordinate S3 functions
• add.tree function (for plotting with plot.ordinate)

OTHER CHANGES

• Updated support functions for lm.rrpp to provide better flexibility for different formulas.
• Changed $LM$data in lm.rrpp to be a model frame rather than a data frame, consistent with $model from lm.

BUG FIXES

• Fixed issue with transformation of dependent variable -- e.g., log(y) -- in formula for lm.rrpp. The bug was a failure to transform the variable(s).
