Problem with aggregate function after loading questionr about questionr

[juba]

Are you sure the problem comes from questionr ? I can't reproduce it here with the following aggregate example :

aggregate(state.x77, list(Region = state.region),FUN=function(x) c(mean =mean(x), s_d =sd(x)))

This comes from package:memisc and only applies to aggregate.formula. memisc has its own "improved" version of aggregate formula i.e. aggregate(y ~ x, data = foo, FUN = mean) becomes aggregate(mean(y) ~ x, data = foo). I'm not sure why it persists after detaching memisc... Anyways, it is not a problem with questionr or really a bug for that matter. Although it is really annoying that someone would change a function like aggregate in their package
