[R] Supressing printing from a function: ecdf

[Ivar Herfindal]

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
