[R] Help to extract results from lme.object

[Auston]

Hi list,

Would someone please give me a hint how to extract the between and within
subject StdDev from "lme" fit? Below is the output from the fit, but I couldn't
find the number 0.3927714 anywhere in the fitted object. Thanks in advance for
your help!


Random effects:
 Formula: ~1 | group
        (Intercept)  Residual
StdDev:   0.3927714 0.7857085



Best,

Auston
