Hi all,
?quantile states:
names: logical; if true, the result has a names attribute. Set to
‘FALSE’ for speedup with many ‘probs’.
Unless I'm missing something entirely, the "set to FALSE for speedup" part
appears to no longer apply. I could trace it back to the introduction of the auxiliairy
function 'format_perc':

format_perc() factored out of quantile.default() + an RFC on "export"
I'm not sure if the intend is to modify the code to comply to the
documentation, or the other way around. ;-) I'm willing to prepare a patch if
informed.
