[R] quantiles with approximately the same number of data points within each quantile?

[Rui Barradas]

Hello,

Use function ?quantile.
See this example, each group has exactly, not approximately, 25 elements.

x <- rnorm(100)

qnt <- quantile(x)
tapply(x, findInterval(x, qnt, rightmost.closed = TRUE), length)

Hope this helps,

Rui Barradas
