R help - Jul 2004 - questions about R

Hi,
 
I try to compute critical value for multivariate normal distribution, and I find
the crit(fit, const = c(0, 1), d = 1, cov = 0.95, rdf = 0) which seems to
compute critical value. However, I can't compute right critical value for
multivariate normal distribution which I want. I don't know how to solve my
question. I send my question in the file. Would you help me to solve it, please?
My English is not very well, but I appreciate you very much.

one possibility is to invert the P-value function `pmvnorm' from
package `mvtnorm' using `uniroot' - There is FORTRAN 90 code solving
this
problem available from Alan Genz' homepage at
