[R-sig-teaching] Rcmdr

[John Fox]

Dear Robert,

The Rcmdr only activates menu items that are applicable to the current
data set. In the case of a two-sample t-test, the data set must include
at least one two-level factor and one numeric variable. Does that
explain the behaviour you noted?

I hope this helps,
 John
