Hi, This should do it, for details, see ?apply a <- matrix(rnorm(1),100,100) t(apply(a, 1, quantile, probs = c(.3, .5))) Basically you apply() the quantile function to each row (the 1, 2 would indicate columns) in the object 'a'. HTH, Josh On Wed, Oct 6, 2010 at 10:20 PM, Takos wrote: >

Read the help page for the quantile function (the whole page, there is a lot of good detail in there), the 2nd reference on the page should also be a helpful read. -- Gregory (Greg) L. Snow Ph.D. Statistical Data Center Intermountain Healthcare greg.s...@imail.org 801.408.8111 > -Origin
