Prepend a vector.

This is a companion to append() to help merging two lists or atomic vectors. prepend() is a clearer semantic signal than `c()` that a vector is to be merged at the beginning of another, especially in a pipe chain.

Usage
prepend(x, values, before = 1)
Arguments
x
the vector to be modified.
values
to be included in the modified vector.
before
a subscript, before which the values are to be appended.
Value

A merged vector.

Examples
x <- as.list(1:3)

append(x, "a")
prepend(x, "a")
prepend(x, list("a", "b"), before = 3)
