Hello,
Do you know a R implemented normality test like the shapiro test but more
suitable for large data set ?
Thanks,

Hello R Users,
Suppose I have data with the structure below:
Group_Name Pre_Test Post_Test
Grp_A xxx xxx
Grp_A xxx xxx
Grp_A xxx xxx
...
Grp_B xxx xxx
Grp_B xxx xxx
...
Grp_Z
One of:
?by
?aggregate
?ave
Next time include the package name where these functions come from AND
code that creates an example data situation and you will increase your
probability of getting a more prompt and complete reply.
