need help subsetting a dataframe

["Kirk R. Wythers" <kwythers@forestry.umn.edu>]

Can someone get me started subsetting a dataframe? I want to create a
new dataframe that contains all of the rows of the original dataframe
where a column "species" is equal to "x".

splus 6 for linux

Thanks in advance,

Kirk
