I believe it is in the Rcmdr package, which requires the car library to be loaded.
You can also perform an ANOVA using the absolute value of the deviations from each
respective group mean, which is what Levene's Test does.

Dear Maurice,
Brian Ripley once posted a function for Levene's test to the R-help list. I
incorporated a slightly modified version in the Rcmdr package. Since the
function is very simple, I'll just list it here (it doesn't make sense to
use the Rcmdr package just for this function):
