Hi,
Try ?match
b[match(d,a)]
#[1] "Joe" "Bob" "Dick"
A.K.
I have three vectors as follows:
> a <- c('A','B','C','D','E')
> b <- c('Tom','Dick','Harry','Bob','Joe')
> d <- c('E','D','B')
Subsetting b by using d on a, with b[a %in% d], gives the names in the order
they appear in b:
> b[a %in% d]
> [1] "Dick" "Bob" "Joe"
But I'd like them to show in the order in d, as "Joe" "Bob" "Dick". What is the
easy way to do this?
Thanks.
