Hi there, When i do
mean(fl[1:20], na.rm=T) sd(fl[1:20], na.rm=T) I get 20 Results, but now I'd like to know from how many numbers my mean and sd are calculated. How to I use the length() for this, or is this possible? Because there are missing values in some, but not in all columns. So there should be a different count of numbers.
