Hi all,

I have a data frame in which one column(PUNTAR) is of character type. What I want is to retrieve is the frame but only with those rows matching elements of PUNTAR with a list characters (e.g c("IX49","IX48") )

Year TUR STODNR PUNTAR

1994  9412 94020061     IX49
1994  9412 94020062     IX48
1994  9412 94020063      X32
1994  9412 94020065      X23
1994  9412 94020066      X27
1994  9412 94020067     XI19
1994  9412 94020068     XI16

1994  9412 94020072      X18
1994  9412 94020073     II23

1994 9412 94020074 XII33
1994 9412 94020075 XII31 "my.function"("frame") should be then equal to
