R help - Oct 2011 - anova.pgls not working for factors in univariate analyses

Hi there,



I am running simple univariate analyses via CAPER and when trying to obtain a
summary of my model using:





anova.pgls(model1)



It works for my analyses containing continuous explanatory variables but not for
those containing categorical explanatory variables (both have a continuous
response).  For those analyses involving categorical explantories I am getting
the error message:



error in terms.formula(formula, data = data) :
  invalid model formula in ExtractVars





summary.pgls(model1) works just fine for all models so the models involving
categorical explanatories are definitely working, it's just I want the
simplified anova output for ease when simplifying more complicated models
later...



Anyone know of the appropriate anova.pgls alternative?  Sorry this is such a
simple question!



Thanks!



Sarah
