[R-sig-ME] Print out of function lmer

[Ben Bolker]

 [keeping r-sig-mixed-models in cc: list]

  It's admittedly a bit obscure, but the ?summary.merMod page shows
that the 'print' method for 'summary.merMod' objects has an argument
called 'ranef.comp', which is described as follows:

ranef.comp: character vector of length one or two, indicating if
          random-effects parameters should be reported on the variance
          and/or standard deviation scale.

(This argument should probably be called varcorr.comp rather than
ranef.comp ...)

Similarly, the ?VarCorr.merMod help page has a note saying:

The ‘print’ method for ‘VarCorr.merMod’ objects has optional
     arguments ‘digits’ (specify digits of precision for printing) and
     ‘comp’: the latter is a character vector with any combination of
     ‘"Variance"’ and ‘"Std.Dev."’, to specify whether variances,
     standard deviations, or both should be printed.
