[R] error in qr(x)

[Martin Wegmann]

Hello, 

I get the following prompt when tring to compute rlm:

> x<-rlm(core.e, na.action=na.omit)
>Error in qr(x) : NA/NaN/Inf in foreign function call (arg 1)

I checked with is.finite and is.infinite but in both cases i get FALSE and my 
missing values are substituted by NA. 

what does this error prompt mean and how do I solve it?

thanks in advance, cheers Martin
