gf_lm()
The gf_lm() function overlays the best-fitting regression line on a scatter plot when chained onto gf_point(). Example: # adds a regression line gf_point(Thumb ~ Height, data = Fingers) %>% gf_lm( color = "orange", size = 2 )
gf_jitter()
The gf_jitter() function will generate a jitter plot. A jitter plot is a point plot (similar to a scatter plot, such as gf_point()) but the points are moved slightly ("jittered") so that they do not overlap as much. This can help make it easier to ...
gf_vline()
The gf_vline() function will add a vertical line onto a plot. You can plot the line by referencing a value in a data frame (Example 1), or by specifying the point along the axis where the line should run through (Example 2). Example 1: # Save the ...
b1()
The b1() function will calculate the b1 value for a model. Example 1: Below are various methods for indexing the model in the argument of the b1() function (they will all produce the same output). # Method 1: Find the b1 value for the Sex model of ...
