corrChord

This function creates a chord plot of correlations between variables in a dataset.

corrChord(mat, threshold = 0, circle = FALSE)

Arguments

mat

A square correlation matrix to visualise.

threshold

A numeric value indicating the minimum absolute correlation value to display in the plot.

circle

A logical value indicating whether to use a circular layout (TRUE) or linear layout (FALSE), default is FALSE.

Value

A chord plot displaying correlations.

Details

When using a large amount of data, this plot can quickly become over complicated. It is recommended to filter the correlations using the threshold argument to simplify the visualisation.

Examples

cm <- cor(mtcars)

corrChord(mat = cm,
          threshold = 0.8)


corrChord(mat = cm,
          threshold = 0.8,
          circle = TRUE)
