I want to apply a more complicated function than what I use in my example,
but the idea is the same:
Suppose you have a data frame named x and you want to a function applied to
each variable, we'll just use the quantile function for this example. I'm
trying all sorts of apply functions, but not having luck. My best guess
would be:
sapply(x, FUN=quantile)
And how does that not work? For me, it does:
test <- data.frame(a = rnorm(100), b = rnorm(100), c = rnorm(100))
sapply(test, quantile)
You should say what you tried and most importantly, *how* you are not
having luck, i.e., what errors or unexpected results you are getting.
Using small examples like the 'test' data.frame can also help clear up
misunderstandings.
