Here's my 0.0162 Euros (at current conversion rates):

For R 2.4.0, announce that LC_PAPER will become the default environment
variable used to set the default R papersize and then not set
R_PAPERSIZE by default (ie. in build scripts, etc.)

However, If someone sets R_PAPERSIZE in their site or local profile,
this will supercede the LC_PAPER setting. This would allow for a R
setting that may need to be different than the system default.

Doing this for 2.4.0 (as opposed to 2.3.x) would give folks notice and
time to consider the impact on their local installations and code, while
enabling future users to take advantage of the standard.

I think that in general, R should abide by published standards unless
there are very compelling reasons not to.

HTH,
