cdf of the standard normal distribution
Dear Experts,
I need to calculate the cdf of the standard normal distribution, i.e.
H(x) = 1/sqrt(2*pi) integral(exp(-z^2/2) dz), where z is b/w -infi to
infi.
I know there should be a way to do it in R, but did not know to do it.
I'd appreciate any help you could offer.

returned values of glim() in S PLus and glm() in R
Dear Experts,
In glim() of S Plus, one of the returned values is "var", the estimated
variance matrix of coefficients. However, in glm() of R (there is no
glim() in R), "var" is not one of the returned values. Anyone know what
could I get the varience matrix of coefficients in glm() in R?
As a novice in R and S+, I'd appreciate your help
Sincerely,
Charlie Liu

How to change the label position in axis() ?
Dear R People,
I'm working on a plot function to produce the graph shown below. One of
the features my supervisor does not like is that the labels in the Y-
axix are shown vertically. Is there a way to change that to horizontally
?
This is the axix() function I used :
axis(2,at=seq(nstrat),labels=snames)
The labels (snames) are: SEV1:HU:C, SEV1:MU:C, SEV1:MU:L, SEV1:RT:C
and SEV1:RT:L,

bug in the new version R1040
Hi,
I just downloaded the latest version of R - 1040. I'm doing the project
of converting CATREG - a statistical software writen in S Plus to R.
However, when I copied my R codes to the 1040 bin directory and resource
my codes, I got the following error message, this never happened in my
1030 or 1010 versions of R. Anyone one know what's wrong with 1040?
THanks
