[R] boxplot&levels

[SKÁLA Zdeněk]

Dear all,
is there a simle way (other than playing with subset()) to manipulate order of levels when calling boxplot(my.vector~my.factor) - i.e. to force boxes being plotted in another order than (alphabetic) default for levels?
(I believe I have seen this topic at R-help some time ago but am unable now to find it - apologies if it really was already answered)

Many thanks!
