unfortunately storage.mode won't run.
>storage.mode(MEAN) = "numeric"
Default in as.double.default(list(Group.1 = c(1, 2, 3, 4, 5, 6, 7, 8, 9, :
(list) Object can't change in 'double'
I also tried:
MEASURE <- sapply( MEAN, as.numeric )
But then, the first colum is +1 greater and the second colum is +1)*10 greater.
Maybe somebody has a idea.
