Hi Steven, See the prob argument under ?quantile. The following should be what you want: tapply(x, l.c.1, quantile, prob = 0.75) HTH, Jorge * * On Thu, Mar 24, 2011 at 7:18 PM, Steven Ranney <> wrote: > All - > > I have an example data frame > > x l.c.1 > 43.38812035 085 > 47.5571

Just have a look at ?quantile and the probs argument. tapply(x, l.c.1, quantile,probs=0.75) Anyway, quantiles and quartiles are not the same. I guess you meant the 3rd quartile. > All - > > I have an example data frame > > x l.c.1 > 43.38812035 085 > 47.55710661 085 > 47.55710661 085
