[R] p-VALUE calculation

[Bill.Venables at csiro.au]

Is this the kind of thing you mean?

> wData <- within(wData, {
+ z <- (weigth - mean(weigth))/sd(weigth)
+ "p-value" <- 2*pnorm(-abs(z))  ## 2-sided
+ rm(z) })
> wData
  employee_id weigth   p-value
1         100    150 0.3763641
2         101    200 0.9081403
3         102    300 0.1547139
4         103    180 0.6722391 


(You might want to think about the spelling of 'weigth' a bit more.)

Here is my dataframe with 1000 rows:

employee_id         weigth       p-value         

100                     150
101                     200
102                     300
103                     180
.....

My question:

     how can I calculate the p-value in R for each employee? the
distribution of the weigth will be established from the above 1000 samples.
