For values in list above a number set boolean (true, false) in R

Question

Suppose, I have a list

a <- c(3, 5, 2, 7, 9)

and I want to do a vector operation, something like:

a_greater_than_five <- a[a>5]

but I want results something like below:

a_greater_than_five <- c(false, false, false, true, true).

Using `[]` means you are subsetting your data. so doing `a[a>5]` will store values which are greater than `5` i.e. `7` and `9` — Sowmya S. Manian, Jun 01 '16 at 16:03

If

 a <- c(3, 5, 2, 7, 9)

then simply

a > 5   
# [1] FALSE FALSE FALSE  TRUE  TRUE
