I have 3 columns of numbers, and i want to find the mean of each
separately, and then the mean of all of the means.
ive tried:
av3daysB<- mean(mean(avr1), mean(avr2), mean(avr3))
av3daysB
sapply(list(avr1, avr2, avr3), mean)
mean(c(avr1, avr2, avr3))
but it only gives me the mean of the first column (avr1)
Any suggestions?
Thanks,
Emilija
