Cap options

Source: R/shapes_caps.R
cap_options.Rd

These functions construct various sorts of caps. They construct a matrix that can be supplied as the shape argument in gizmo_barcap().

Usage

cap_triangle()

cap_round(n = 100)

cap_arch(n = 100)

cap_ogee(n = 100)

cap_none()

Arguments

n

An <integer[n]> number of points to use for the cap.

Value

A <matrix[n, 2]> with coordinates for points on the brackets.

Details

When designing custom cap shapes, the expectation is that the first point starts at the (0, 0) coordinate and the last point ends at the (0, 1) coordinate. The first column follows the orthogonal direction of the bar whereas the second column follows the direction of the bar.

Functions

  • cap_triangle(): An equilateral triangle with n = 3 points.

  • cap_round(): A semicircle.

  • cap_arch(): Two circular arcs forming an equilateral Gothic arch.

  • cap_ogee(): Four circular arcs forming an 'ogee' arch.

  • cap_none(): No cap.

Examples

plot(cap_arch(), type = 'l')
