Draw a triangulation mesh object

Description

Plots an fm_mesh_2d() object using standard graphics.

Usage

## S3 method for class 'fm_mesh_2d'
lines(x, ..., add = TRUE)

## S3 method for class 'fm_mesh_2d'
plot(
  x,
  col = "white",
  t.sub = seq_len(nrow(x$graph$tv)),
  add = FALSE,
  lwd = 1,
  xlim = range(x$loc[, 1]),
  ylim = range(x$loc[, 2]),
  main = NULL,
  size = 1,
  draw.vertices = FALSE,
  vertex.color = "black",
  draw.edges = TRUE,
  edge.color = rgb(0.3, 0.3, 0.3),
  draw.segments = draw.edges,
  rgl = deprecated(),

  ylab = "",
  ...
)

Arguments

x	An fm_mesh_2d() object.
...	Further graphics parameters, interpreted by the respective plotting systems.
add	If TRUE, adds to the current plot instead of starting a new one.
col	Color specification. A single named color, a vector of scalar values, or a matrix of RGB values. Requires rgl=TRUE.
t.sub	Optional triangle index subset to be drawn.
lwd	Line width for triangle edges.
xlim	X-axis limits.
ylim	Y-axis limits.
main	Deprecated.
size	argument cex for vertex points.
draw.vertices	If TRUE, draw triangle vertices.
vertex.color	Color specification for all vertices.
draw.edges	If TRUE, draw triangle edges.
edge.color	Color specification for all edges.
draw.segments	If TRUE, draw boundary and interior constraint edges more prominently.
rgl	Deprecated
visibility	If "front" only display mesh faces with normal pointing towards the camera.
asp	Aspect ratio for new plots. Default 1.
axes	logical; whether axes should be drawn on the plot. Default FALSE.
xlab, ylab	character; labels for the axes.

Value
