Displays of scatter plot and adds a smoothing line, using ggplot2.

ggassoc_scatter(data, mapping, na.rm = FALSE,
axes.labs = TRUE, ticks.labs = TRUE, text.size = 3)

Arguments

data

dataset to use for plot

mapping

aesthetic being used. It must specify x and y.

na.rm

logical, indicating whether NA values should be silently removed before the computation proceeds. Default is FALSE.

axes.labs

Whether to display the labels of the axes, i.e. the names of x and y. Default is TRUE.

ticks.labs

Whether to display the labels of the categories of x and y. Default is TRUE.

text.size

Size of the association measure. If NULL, the text is not added to the plot.

Details

Kendall's tau rank correlation between x and y is displayed in upper-left corner of the plot.

Smoothing is performed with gam.

This function can be used as a high-level plot with ggduo and ggpairs functions of the GGally package.

Value

a ggplot object
