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

Hi
I am a beginner R user and need a little help with the subset function.
I have a dataset with columns; TOWER,TAG.ID, DATETIME (POSIXct class) and I
would like to subset my data by specific TAG.ID (e.g TAG.IDs 12:20 and
192:212). Is there an easy way to preform this operation?
Thanks
Bryant
