This function runs an expression multiple times, and combines the result into a list. If there are no results, then this function will return a list of length 0 (list()). This function is equivalent to replicate, but will always return results as a list.

mods <- rlply(100, lm(y ~ x, data=data.frame(x=rnorm(100), y=rnorm(100))))
hist(laply(mods, function(x) summary(x)$r.squared))
