R Calculate Standard Deviation

R Calculate Standard Deviation. Standard deviation in statistics, typically denoted by σ, is a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values in a set of data. Finding the standard deviation of the values in r is easy.
