[R] Standard Deviation in R

[arun]

Hi,
Please check this link:
http://stats.stackexchange.com/questions/25956/what-formula-is-used-for-standard-deviation-in-r

A.K.


It is my understanding that the R function SD finds the standard deviation of a random variable or a list. Please consider the following list: { 1, 2, 3 }. I claim that the standard deviation of this list is not 1. However, the following R statement returns 1:
         sd ( seq(1:3) )
What am I missing?

I thank the group in advance for their responses.

Bob
