The formula specifies the relationship between the dependent variable and the independent variables, and the data frame contains the data for the variables.<\/p>\n<p>For example, the following code performs linear regression on the data in the data frame <code>cars<\/code> to predict the mpg (miles per gallon) of a car based on its weight (wt):<\/p>\n<p><code>lm(mpg ~ wt, data = cars)<\/code><\/p>\n<p>The output of this code is a list of objects, including the coefficients of the linear regression model.
