I would like to ask you about shapiro test in R. How can I refer to a variable in test result?
r<-shapiro.test(reszty)
r
Shapiro-Wilk normality test
data: reszty
W = 0.9226, p-value = 4.967e-07
I would like to refer to w and to p-value.
In general, for function calls in R you can extract information after assigning to a variable doing this:
r<-shapiro.test(reszty)
r$statistic (for W) or r$p.value (for p-val)
or you can not assign to a variable, but extract straight away:
shapiro.test(reszty)$p.value
