Do you know a R implemented normality test like the shapiro test but more suitable for large data set ?
Try installing the "nortest" package.

See: http://finzi.psych.upenn.edu/R/Rhelp08/archive/136160.html But the issue really comes down to the fact that the questions: "exactly normal?", and "normal enough?" are 2 very different questions (with the difference becoming greater with increased sample size) and while the first is the easier to answer, the second is generally the more useful one. Hope this helps,
