pnorm, relative accuracy in the tails
...here lambda(x) is the
hazard rate for the normal distribution. Is there a way to calculate
lambda(x) without using pnorm() ?
Any help would be appreciated.

Length of a string
Hi,
Suppose I have created something like this in R:
foo <- "myfoo"
and I want to find out the number of character in foo (in other words, R
should return 5 since "myfoo" has 5 charactors.
How can I do it? I tried:
length(foo)
but it returned 1.
Cheers,
Kevin

function sort.list()
...ng order()
order(c(0, 2, 10, 11, 4))
[1] 1 2 5 3 4
Of course
rank(c(0, 2, 10, 11, 4))
1] 1 2 4 5 3
gives the correct result.
Am I missing something obvious here ?
Cheers Ole

correlated random effects in GLMMGibbs ?
Dear R-users,
I wondered if anyone has extended GLMMGibbs to include correlated
random effects, and if so, whether they would be willing to let me
use their code?
Jonathan Myles has no plans to extend glmm in this manner within the
foreseeable future.
With thanks,
Patty

defining and plotting functions thanks to equation
Hi R lovers!
Are there any means to define and plot a function given the equation that
specifies the function?
For example I'd like to plot and work with the Gumbel Distribution density
defined by
Lambda(x)=exp(-exp(-x))
My question may appear very simple but I haven't got an idea yet about how
to do that. I could plot something with x a vector/set of value but I don't
know how to
