Hi Elham, The error message is pretty explicit. Check your dataset for missing values.

Hi Elham,
The error message:
Error in if (S == 0) { : missing value where TRUE/FALSE needed
means that for at least one S, the value is missing. The best advice I
can give you is to load the data frame X1 as in your code above, and
try something like:
which.na<-function(x) return(which(is.na(x)))
sapply(X1,which.na)
You will then get a list of the positions of any NA values in X1.
Jim
