[R] non-conformable arguments

[Thierry Onkelinx]

We need enough information to run your code on our computer and get the
same error as you. In this case we are missing the data. See e.g.
http://adv-r.had.co.nz/Reproducibility.html If you can't provide the
original data, then try to make a (small) example which reproduces your
problem.

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
