Reporting Point-Biserial Correlation

If I am using a point-biserial correlation can I treat it as I would a regular Pearson's R and use the R-sq to explain variance?

The point-biserial is mathematicly the same as the Pearson. That is, if you perform a Pearson correlation using one variable (eg sex) coded 0,1 you get a point-biserial. I GUESS that you can square the resulting "r" and interpret it as usual.
