Havent seen anything on R-devel yet on this topic, but if the elseif statement on line 43 of seq.default was
else if (length.out == 0) double(0) instead of else if (length.out == 0) numeric(0) then that *might* satisfy Richard A. O'Keefe's comment for length=0:n cases >> storage.mode(seq(length=0)) RichOK> [1] "integer" >> storage.mode(seq(length=1)) RichOK> [1] "double" marcus >>> Martin Maechler <[EMAIL PROTECTED]> 10/12/2004 9:34:11 PM >>> I'm diverting to R-devel, where this is really more appropriate.
