- But note this behavior: [1] "a" "" "c" suggesting that in S-Plus, "" is the analog of numeric NA. You could write: [1] "a" "b" "c" "" "e" [1] F F F T F The string "NA" is certainly a bad choice, as i

- I wrote a C program and an interface to R that computes running medians (for N odd) of matrix columns (also works for a single vector). You'll have to modify the interface for S-Plus. You can find th

- The Fourier transform of a *complex* N-vector "z" is another complex N-vector "w". If "z" is *real*, then the second half of "w" is the complex conjugate of the first half, so it can be ignored. For
