[R] overleap an iteration within a for-loop when error message produced

[Nicolas Berkowitsch]

Dear R-list member,

I'm using the function pmnorm() (-->library(mnormt)) within a for-loop. 
Certain parameter values leads to an error message:
  "(In sqrt(diag(S)) : NaNs produced, In sqrt(1/diag(V)) : NaNs 
produced, In cov2cor(S) : diag(.) had 0 or NA entries; non-finite result 
is doubtful)"
obviously because "NaNs" were produced.
Is it possible to tell R that it should overleap the iteration which 
produce the error message?

Here is an example code (does not lead to an error message):

for (subject in 1:10) {

     p[subject] = pmnorm(x = subject*c(-.3,1), varcov = diag(2))

}

Assume that the 5th iteration (subject=5) leads to the error message. 
How can I tell R to continue with the 6th iteration?

Thanks a lot for you help and input,
Nicolas
