    I have the following dataframe:

temp<-data.frame(a=c(1,1,2), b=2:4, c=1:3)
row.names(temp)<-c("D", "E", "F")
   a b c
D 1 2 1
E 1 3 2
F 2 4 3

    I would like R to tell me which rows has value "a" equal to 1. The
answer is the first row and the second row, or row D and row E. Which
function should i use? function subset? function which?
