The easiest way is to subset your vector with c(TRUE, FALSE) to keep
only the odd
Ms. White:
Unless I have seriously misjudged, you really really really need to go
through an R tutorial -- An Intro to R ships with R, but there are
many on the web -- before posting here further. You do not appear to
have made much of an effort to learn even the basics, and I consider
it unfair t
## these functions assume the argument is integer
odd <- function(x) x%%2 != 0
even <- function(x) x%%2 == 0
evenb <- function(x) !odd(x)
odd(1:10)
even(1:10)
evenb(1:10)

Might be a trivial question but how to identify the odd and even indices of a
vector?
x = c(1,z,w,2,6,7)
el of odd indices= 1,w,6
el of even indices= z,2,7
