I have found following problem: I have a vector:
a<- c(1.04,1.04,1.05,1.04,1.04)
I want a mean of this vector:
mean(a)
[1] 1.042 which is correct, but:
mean(1.04,1.04,1.05,1.04,1.04)
[1] 1.04 gives an incorrect value. how is this possible?
the x that is averaged is only the first 1.04, the other numbers go into mean's
... argument and are ignored.
