[R] extracting selected rows, based on a 'list' of values

I was trying to extract certain rows from a table. For example, if the value in the first column is "a", "d", "k", or "z", then I would like to extract these rows. In other words, if the value in the column is also an element in my list (a,d,k,z), then I would like to extract the row.  

I've looked in the archives and the solutions I could find were restriced to the value in the row name being a single element.  

thanks for the help,
