popular R packages
More seriously : I don't think relative numbers of package downloads can
be interpreted in any reasonable way, because reasons for package
download have a very wide range from curiosity ("what's this ?"), fun
(think "fortunes"...), to vital need tthink lme4 if/when a consensus on
denominator DFs can be reached :-)...). What can you infer in good faith
from such a mess ?
So when we have messy data with measurement error, we should just give up? Doesn't sound very statistical! ;) Hadley
