Hello,
I was just wondering whether there is a quick way to divide a vector of
data into four groups defined by the quantiles?
i.e.
0-25%
25-50%
50-75%
75-100%
Many thanks

check at cut() and split(), e.g.,
x <- rnorm(100)
qx <- quantile(x)
ind <- cut(x, qx, include.lowest = TRUE)
split(x, ind)
I hope it helps.
Best,
Dimitris

Hello,
I was just wondering whether there is a quick way to divide a vector of

i.e.
0-25%
25-50%
50-75%
75-100%
Many thanks
