This is a companion to base::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.
Life cycle
prepend() is experimental, expect API changes. We are still
figuring out what vector tools belong in rlang.
