WebR-squared is comparing how much of true variation is in fact explained by the best straight line provided by the regression model. If R-squared is very small then it indicates you should consider models other than straight lines. • ( 6 votes) tbeatty 11 years ago WebAs you can see based on the previous output of the RStudio console, we’ll use the value 5 for this example. Now, we can calculate the square of this data object by using the ^ symbol: x ^2 # Calculate square of data object # 25 The RStudio console shows the result: The square of 5 is equal to 25.
