I have 2 extracted data sets from a dataset called babies2009( 3 vectors count, name, gender )
One is girls2009 containing all the girls and the other boys2009. I want to find out what similar names exist between boys and girls.
I tried this
common.names = (boys2009$name %in% girls2009$name)
When I try
babies2009[common.names, ] [1:10, ]
all I get is the girl names not the common names.
I have confirmed that both data sets indeed contain boys and girls respectively by doing taking a 10 sample...
boys2009 [1:10,]
girsl2009 [1:10,]
How else can I compare the 2 datasets and determine what values they both share. Thanks,
