In R programming, variance is a statistical measure that describes how spread out a set of values are from the mean. The formula for calculating variance is Var(x) = (1/(n-1)) * sum((x[i] - mean(x))^2), where x is the vector or data frame containing the values, n is the number of values in x, and x[i] is each individual value.
