Dear all,

I have a data.frame like this 

ID         VAR1
11           blaaal
121         blalda
121          adada
234        baada
231         ddaaa
231         baada
...           ...

and I have another vector of ID, say, c(121,234,231)
How could I collect all the observations start with ID from c(121,234,231) ?


Thanks

All the Best,
Desper
