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 Em 06-12-2013 19:47, Anika Masters escreveu:
What is a "good" way to create quantiles with approximately the same number of data points within each quantile? ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
