Dear R-help,
Is the following a bug of pmvnorm?
R-matrix(c(1,.5,.5,1),2,2)
pmvnorm(lower=c(-Inf,-Inf),upper=c(Inf,Inf),corr=R)
It returns,
[1] 0
attr(,error)
[1] 0
attr(,msg)
[1] Normal Completion
But I think it should return 1.

Dear R-help,
How can I replicate the beautiful math plot found in the right-hand side of
http://www.r-project.org/screenshots/desktop.jpg? I tried the following code
but didn't obtain something as beautiful.
r - seq(-10, 10, len=100)
y - cos(r^2)*exp(-r/6)
par(pty=s)
plot(r,y,type=l)
Thanks

Dear R-help,
This is my first R day. I want to ask some more beginner's questions.
Q1. How can I obtain the covariance matrix for parameter estimates of a
multiple regression? I checked ?lm but didn't get the information.
Q2. How can I see the old graphs in the graph window?
Q3. Can R plot
