Hello,
Not answering directly to your question, if the sample size is a
documented problem with shapiro.test and you want a normality test, why
don't you use ?ks.test?
m <- mean(HP_TrinityK25$V2)
s <- sd(HP_TrinityK25$V2)
ks.test(HP_TrinityK25$V2, "pnorm", m, s)
Hope this helps,
Rui Barradas

Dear R users,
Please help with with this maybe basic question. I am trying to see if my
data is normal but is a large file and the test does not work.
I keep getting the message : "Error in shapiro.test(x = HP_TrinityK25$V2)
: sample size must be between 3 and 5000"
thanks!
shapiro.test(x=HP_TrinityK25$V2)
Error in shapiro.test(x = HP_TrinityK25$V2) : sample size must be between 3
and 5000
##Note:
HP_TrinityK25= my file
HP_TrinityK25$V2= data in my file
