I'm sorry about that. Second line should be
attach(yourdata)

Hi,
You are right the == doesn't work, but there's a workaround using regular
expressions:
flist<-"fun|food"
grep(flist, data$label)
will give you the vector [2 4] which are the numbers of the rows of
interest!

Hi,
I have loaded a dataset in R :
data =
label freq1 freq2
news 54 35
fun 37 21
milk19 7
food 3 3
etc
And I have a vector
flist<-c("fun","food")
Now I want to use the vector 'flist' for selecting these values from 'data'
so that I get the followin
7 matches
