Dear list members,
I'm quite new to R, and though I tried to find the answer to my probably
very basic question through the available resources (website, mailing
list archives, docs, google), I've not found it.
If I try to use the integrate function from within my own functions,
my functions

Your function jjj is not vectorized.
Try this:
jjj - function(www) sapply(www, function(x)2*integrate(dnorm,0,x)$value)
plot(jjj, 0, 5)
It should work.
Yes it does. Thanks!
Thinking of it, it now starts to make some sort of sense that integrate
should return a
Hi,
Many thanks for the explanation.

Guess: because integrate itself expects a vectorized function ?
