[R] Fw: modified mankendal

[Jim Lemon]

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
