In Morpho: Calculations and Visualisations Related to Geometric Morphometrics

plot lines between landmarks

Description

add lines connecting landmarks to visualise a sort of wireframe

Usage

lineplot(
  x,
  point,
  col = 1,
  lwd = 1,
  line_antialias = FALSE,
  lty = 1,
  add = TRUE
)

Arguments

x	matrix containing 2D or 3D landmarks
point	vector or list of vectors containing rowindices of x, determining which landmarks to connect.
col	color of lines
lwd	line width
line_antialias	logical: smooth lines
lty	line type (only for 2D case)
