An interactive function that will generate a scatterplot of two variables, then allow the user to click the plot in two locations to draw a best fit line. Residuals are drawn by default; boxes representing the squared residuals are optional.
plot_ss(x, y, data, showSquares = FALSE, leastSquares = FALSE)
| x | the name of numerical vector 1 |
|---|---|
| y | the name of numerical vector 2 |
| data | the dataframe in which x and y can be found |
| showSquares | logical option to show boxes representing the squared residuals |
| leastSquares | logical option to bypass point entry and automatically draw the least squares line |
