ifelse() where pmin() or pmax() is more appropriateifelse(x > M, M, x) is the same as pmin(x, M), but harder
to read and requires several passes over the vector.

The same goes for other similar ways to censor a vector, e.g.
ifelse(x <= M, x, M) is pmin(x, M),
ifelse(x < m, m, x) is pmax(x, m), and
ifelse(x >= m, x, m) is pmax(x, m).
