Thanks for the feedback Patrizio - but your function is performing the
shapiro.test on columns instead of rows...
I tried:
nt<-data.frame(#a dataframe with 6 columns and 9 rows)
nr <- nrow(nt)
test <- apply(nt, nt[1:nr,], shapiro.test)
Error in ds[-MARGIN] : invalid subscript type 'list'
The second argument to apply needs to be a (short) numeric vector.
Your request suggest you simply want the number 1, since that would
tell apply to use the function on rows.
fred<-data.frame(sapply(test,function(x)c(x$statistic, x$p.value)))
But picked up the error above. Do I still require a loop to apply
this over
rows?
