It is _just two days_ since someone asked: https://stat.ethz.ch/pipermail/r-help/2006-April/092437.html
and that question was answered several times in the recent past, so I at least declined to answer it again. A quick search via RSiteSearch() shows several explanations http://finzi.psych.upenn.edu/R/Rhelp02a/archive/68606.html http://finzi.psych.upenn.edu/R/Rhelp02a/archive/35599.html http://finzi.psych.upenn.edu/R/Rhelp02a/archive/7549.html and even an (approximate) solution http://finzi.psych.upenn.edu/R/Rhelp02a/archive/42932.html If non-linearity matters, simulation can be very effective.
