Dear R helpers

Suppose I have a vector as

vect_1 = c("AAA", "AA", "A", "BBB", "BB", "B", "CCC")

vect_1_id = c(1:length(vect_1))

Through some process I obtain

vect_2_id = c(2, 3, 7), then I need a new vector say vect_2 which will give me

vect2 = ("AA", "A", "CCC")  i.e. I need the subset of vect_1 as per vect_2_id.

Thanking in advance
