Scatter plot function

scatt(
  df,
  x,
  y,
  xs = defx(),
  ys = defy(),
  title = NULL,
  group = NULL,
  col = NULL,
  plot_id = FALSE,
  size = pm_opts$scatter.size,
  alpha = pm_opts$scatter.alpha,
  scale_col = scale_color_brewer(palette = "Set2", name = ""),
  ...
)

Arguments

df: Data frame to plot.
x: Character name for x-axis data.
y: Character name for y-axis data.
xs: See defx().
ys: See defy().
title: Character, passed to ggplot2::ggtitle().
group: Character name of grouping variable.
col: Character name of variable to color the points.
plot_id: If TRUE then subject IDs are plotted rather than points; see the size argument - the size may need to be increased when plotting IDs.
size: Passed to ggplot2::geom_point() or ggplot2::geom_text().
alpha: Passed to ggplot2::geom_point().
scale_col: Discrete scale to use for coloring the points (see default).
...: Not used.

Value

A single plot.

Details

Since this function creates a scatter plot, both the x and y columns must be numeric.
