Dear All,

I am running into two problems with nlme in R (R versions both 0.90.1 and

1. If I try to fit a model with crossed random effects, such as: 

Error in parse(file, n, text, prompt) : parse error

(I can fit that exact same model in SPlus without problems).

2. the anova.lme function does not seem to work with the "Terms" option;
> anova(my.model, Terms=11:14)  
Error in anova.lme(my.model, Terms = 11:14) : Object "noZeroColL" not found

I did not get this error when using SPlus.

Is there an easy fix of these problems, or am I missing something obvious?
