Many thanks all for the response, this worked.

Hi Martin, the "verbose" recommendation below would be very useful if this could be considered for a future release of stats/ecdf.

Regards,
Tolga

Re: [R] Supressing printing from a function: ecdf

Hello

Since the summary.ecdf function first do a "cat", and then calls summary(knots(object),...) , I guess you will obtain the same result without the printing, by just use the latter part of the summary.ecdf function like this:

a <- summary(knots(ecdf(rnorm(100))))["1st Qu."]

Hope this helps

Ivar
