[R] How to say "if error"

[Paul Chatfield]

That's great.  That solves it.  I can work on eloquence later :)  I just  to
sort out that model problem:

 dof<-numeric(10)
for (i in 1:10){
  x<-rnorm(i-1);y<-rnorm(i-1)
  cc <- try(lm(y~x), silent=T)
  if(is(cc,"try-error")) {dof[i]<-NA}
  else {dof[i]<-(summary(lm(rnorm(10)~rgamma(10,1,1)))$coef[1,1])}
}

Thank you!

Paul
