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?
Hi Zbynek,
You're asking the function to give you the mean of a single value. Try this:
mean(c(1.04,1.04,1.05,1.04,1.04))
