Draw a triangulation mesh object

Plots an fm_mesh_2d() object using standard graphics.

Usage

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

# S3 method for 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(),
  visibility = "front",
  asp = 1,
  axes = FALSE,
  xlab = "",
  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

None

Examples

mesh <- fm_rcdt_2d(globe = 10)
plot(mesh)


mesh <- fm_mesh_2d(cbind(0, 1), offset = c(1, 1.5), max.edge = 0.5)
plot(mesh)
