For a simple example of geom_springs() for a regression problem, we plot the first two variables, x1, y1 in the anscombe data set, together with the linear regression line. simple_plot <- ggplot(anscombe, aes(x = x1, y = y1)) + geom_point(size = 4, color = "red") + geom_sm...

method, formulaIf geom="smooth", a loess fit line and confidence limits are added by default. When the number of observations is greater than 1,000, a more efficient smoothing algorithm is employed. Methods include "lm" for regression, "gam" for generalized additive models, and "rlm" for ...
