Describe the characteristics of a pen

Pen plots can include ink from many pens and how they behave may differ. While some of these can be set when a new color is encountered it is often better and less error prone to define them upfront. It further allows you to specify specific axidraw options for each pen, e.g. travel speed.

pen(color, tip_size = NULL, offset = c(0, 0), options = NULL)

Arguments

color	The color that this pen corresponds to.
tip_size	The size of the line the pen leaves on the paper in mm
offset	The x and y offset from the starting pen tip
options	An axi_options object. See the documentation for axi_options() for all the settings.

Value

An axi_pen object

Examples

pen(color = 'forestgreen', tip_size = 2)
#> Color.....    (forestgreen)
#> Tip....... 2 mm
#> Offset.... x: 0 mm, y: 0 mm

# Combine multiple pens
c(
  pen(color = 'forestgreen', tip_size = 2),
  pen(color = 'steelblue', tip_size = 1,
      options = axi_options(speed_down = 15))
)
#> Color.....    (forestgreen)
#> Tip....... 2 mm
#> Offset.... x: 0 mm, y: 0 mm
#> * * *
#> Color.....    (steelblue)
#> Tip....... 1 mm
#> Offset.... x: 0 mm, y: 0 mm
