You can pass true to the na.rm parameter of the var () function to exclude missing values when computing the variance of a vector. We provide programming data of 20 most popular languages, hope to help you! Simply plug in each value in the numeric vector or dataframe into the variance function, and you are on your way to doing linear regression, and many other types of data analysis.
