R users:
Suppose I have a function that takes three numeric arguments x, y, and z,
any of which may be scalars or vectors.
Suppose further that the user takes one of the arguments, say y, as a
vector with the other two as scalars.
Is there an existing R function that will promote the other two arguments
to vectors of the same size?
I know in most cases this is not a problem as the promotion is automatic.
I need this for a function I am writing
and I don't want to write any additional code to do this if I can help it.
