[R] R-squared in mixed-effects models

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?
