[R] Forward of moderated message

One solution among many:

seq(970, 970 - 30*14, by=-30)


If you want to be fancy, a function can be easily written:
seqf <- function(startp, lengthv, byv) {
    seq(startp, startp + (lengthv - 1)*byv, by=byv)
}

seqf(970, 15, -30)
 [1] 970 940 910 880 850 820 790 760 730 700 670 640 610 580 550
