R has a special notation for describing relationships between variables. Suppose that you are assuming a linear model for a variable y, predicted from the variables x1, x2, ..., xn. (Statisticians usually refer
Also, note that we have converted our final output from the tibble to the data.frame class. In case you prefer to work with tibbles, you may remove the last line of the previous R code.Video & Further ResourcesWould you like to know more about the grouping of data frames? Then you ...

you will get the error Error: cannot modify grouping variable. If you get this error, use the ungroup function to remove grouping within a data frame, and then you will be able to mutate any of the variables in the data.
