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
