cleanplots shape and linetype scales for ggplot2 — scale_shape

Discrete shape and linetype scales matching the marker symbols and line patterns of the Stata cleanplots scheme. Combined with scale_color_cleanplots(), these make series distinguishable even when printed in black & white or viewed with colorblindness: markers alternate hollow (dark colors) and solid (light colors) shapes, and series that share a line pattern always differ strongly in lightness.

Usage

scale_shape_cleanplots(...)

scale_linetype_cleanplots(...)

Arguments

...: Additional arguments passed to ggplot2::scale_shape_manual() or ggplot2::scale_linetype_manual().
