[R] R-squared in mixed-effects models

[Richard Gunton]

Hello,

I'm fitting general linear models using the function lme() from the package
nlme.  My variables include a number of covariates and a single random factor,
because the experiment was laid out in blocks.  I'd like to have a statistic to
measure the "proportion of explained variance" from my models.  With ordinary
multiple regression I'd use R-squared, but I can't find any similar items in
the output from lme().  Does anyone know something I can use in these or any
other package?

Thanks,

Richard.
