Subject: inv.logit (package boot) (PR#2394)
Full_Name: Ole Christensen
Version: 1.6.1
OS: linux-gnu
Submission from: (NULL) (130.225.18.176)
In package boot :
> inv.logit(800)
[1] NaN
where it should have been 1.
The problem is caused by exp(x) returning Inf when x is large.
One way of fixing the problem [there may be better ways] would be to include the
line
out[x > 709] <- 1
in inv.logit()
Cheers Ole
