vec_rep()
repeats an entire vector a set number of times
.
vec_rep_each()
repeats each element of a vector a set number of times
.
vec_rep(x, times) vec_rep_each(x, times)

vec_rep()
and vec_rep_each()
work along the size of x
, rather than
its length. For data frames, this means that rows are repeated rather
than columns.
For vec_rep()
, a vector the same type as x
with size
vec_size(x) * times
.
For vec_rep_each()
, a vector the same type as x
with size
sum(vec_recycle(times, vec_size(x)))
