Hello:
The example "integrate(dnorm,0,20000)" says it "fails on many
systems". I just got 0 from it, when I should have gotten either an
error or something close to 0.5. I got this with R 2.12.0 under both
Windows Vista_x64 and Linux (Fedora 13); see the results from Windows
below. I thought you might want to know.
Thanks for all your work in creating and maintaining R.
Best Wishes,
Spencer Graves
