plotSidebars function

Plot Table as Horizontal Sidebars

Plot (x,y) table (matrix or data frame) as horizontal sidebars.

plotSidebars(z, scale = 1, col = lucent("blue", 0.25), ...)

Arguments

• z: data frame or matrix of z-values (e.g., age frequencies) where rows form the plot's y-values and columns describe the grouping variable along the x-axis.

• scale: numeric scale factor controlling the leftward expansion of z-value bars.

• col: colour to fill bars.

• ...: additional parameters used by par and polygon. The user can also pass in two non-formal arguments to control the function:

  lbl -- labels for the x- and y-axis;

  margin -- function to report margin summaries.

Details

Plots z-data as horizontal bars arising from an x-coordinate controlled by the column names of z. The bars extend left along the y-coordinate by z*scale from the central x-coordinate.
