thank you very much
i think it is equal to the %in%
Not exactly. Using %in% ignores the order in which you are
supplying your ids:
> x <- c(a=1, b=2, c=3)
> myids <- c("c", "a")
> x[names(x) %in% myids] # NOT equivalent to x[myids]
a c
1 3
> x[match(myids, names(x))] # equivalent to x[myids]
c a
3 1
