[R] how to append element at last position in array dynamically

[R. Michael Weylandt]

You need to reassign the value of append back to h -- in more
technical terms, this is a pass-by-value rather than pass-by-reference
behavior:

h <- append(h, 9)

This is not likely to be efficient in production code, however.
