I have another question, if I now want to remove multiple id's e.g. id=1 or 4 is there
a simple OR command I can use?

I tried? d2<-(d1[id != 1 | 4, ])

however this does not delete anything

PS? d2<-(d1[id != 4, ]) worked to remove id=4

Thanks

Gina

Is this what you want:

d1[which(id != 4),]

Or just

d1[id != 4, ]
