Trafim,
Could you please provide an example of the data?
I don't believe the sample size to be the driver of the issue you are
having.
For example,
set.seed(20)
x <- rnorm(100)
shapiro.test(x)
returns no error and a p value of 0.5519.
Sample (or actual) data would be helpful in diagnosing the problem.

Hi everybody,
Does anyone know what problem may be with this test.
I am applying 5 different normality tests and use p-values for them, but for
some reason S-W gives me NA, while sample size is 100.
Any ideas?
Thanks a lot!
