What is inappropriate about this? x is a 1D array, so it does not have
column names (or columns). Indeed, the help page says
x: a matrix-like R object, with at least two dimensions for
'colnames'.
The exact same message appears in 1.6.2, more than three years old (and
the earliest version I still have running). If earlier versions did not
have an error message, that was probably a bug.
