d then in
your report mention both density() and weighted.mean(), i.e., a
cleaned up version of the union of your first 2 e-mails..
Thank you for thinking about this and concisely reporting it.

Does your copy of R say that the weights must add up to 1?
?density doesn't say that in mine. But it does check.

Dear R users,
This works as expected:
• plot(density(c(1,2, 3, 4, 5, NA), na.rm=TRUE))
This raises an error
• plot(density(c(1,2, 3, 4, 5, NA), na.rm=TRUE, weights=c(1, 1, 1, 1, 1, 1)))
• plot(density(c(1,2, 3, 4, 5, NA), na.rm=TRUE, weights=c(1, 1, 1, 1, 1, NA)))
This seems to work (it trigge
