operator in a way similar to Python's % overloaded for strings.
Missing values and empty vectors are propagated as usual.
Arguments
- e1

stri_sprintffor syntax- e2
a list of atomic vectors to be passed to
stri_sprintfor a single atomic vector
Details
Vectorized over e1 and e2.
e1 %s$% atomic_vector is equivalent to
e1 %s$% list(atomic_vector).
