issue with Rcmdr

Glad to hear it now works for you.  But speaking more generally, note that R-squared is the squared correlation between the predicted Y and actual Y values.  E.g.

lmout <- lm(y ~ x)
print(cor(lmout$fitted.values,y)^2)

One can use this in any regression setting, even machine learning methods.

... and even more generally, is generally misleading. ;-)

(search "problems with R^2" or similar for why).
