Have you tried removing the NA's beforecalling "rlm"? hth. spencer graves Martin Wegmann wrote:
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
