As I have said before on R-help, it is _already_ fixed in this (and
related cases) and the reasons it is fixed were explained here. If you
read carefully, you will have noticed that some platforms (such as Sparc)
only use 53 bits (+ a guard bit).
Not that I accept that the 53-bit calculation i

This is drifting a bit
Dear Professors Ripley & Murdoch, & others:
If this were just an issue of computations like var(rep(0.02, 10))
producing something other than 0 on certain platforms (e.g.,
combinations of operating systems and microprocessors), then I would
suggest it be documented as an FAQ and left
This is not an R bug, nor it realtes to quantreg. It is not even an
error but a warning.
It is due to the fact that you don't have enough writing permission
and it is related the R.app way of handling package installation.

There has been a recent thread on R-help on this, which resurrected
concepts from bug reports PR#1228 and PR#6743. Since the discussion has
included a lot of erroneous 'information' based on misunderstandings of
floating-point computations, this is an attempt to set the record straight
