Hello,
Try the following.
ix <- with(dataset, TAG.ID %in% 12:20 | TAG.ID %in% 192:212)
dataset[ix, ]
or
ix <- with(dataset, (12 <= TAG.ID & TAG.ID <=20) | (192 <=
TAG.ID &
TAG.ID <= 212))
if the variable is not integer.
Also, read the manual, this, index vectors, is there. (R-intro.pdf).
Hope this helps,
Rui Barradas
