Extract the nth value from a vector

Get the value from a vector with its position.

nth(v, n = 1)

Arguments

v

A vector

n

A single integer specifying the position. Default uses 1. Negative integers index from the end (i.e. -1L will return the last value in the vector). If a double is supplied, it will be silently truncated.

Value

A single value.

Examples

x = 1:10
nth(x, 1)
#> [1] 1
nth(x, 5)
#> [1] 5
nth(x, -2)
#> [1] 9
