Pairwise scatterplot matrix

A scatterplot matrix over selected numeric columns, drawn with facets. Capped at a handful of columns because the number of panels grows quadratically.

Usage

plot_pairs(df, columns = NULL, max_cols = 5)

Arguments

df

A data frame.

columns

Optional character vector of numeric columns to include. If NULL, the first max_cols numeric columns are used.

max_cols

Maximum number of columns to include. Default 5.

Value

A ggplot2 object, or NULL (with a warning) if fewer than two numeric columns are available.

Examples

plot_pairs(iris, c("Sepal.Length", "Sepal.Width", "Petal.Length"))
