autoplot.inla.mesh: An autoplot (ggplot2) method for INLA mesh objects.

In INLAutils: Utility Functions for 'INLA'

Description

An autoplot (ggplot2) method for INLA mesh objects.

Usage

## S3 method for class 'inla.mesh'
autoplot(object, ..., col = "blue", lwd = 0.5,
  linecol = "darkgrey", size = 1.2)

Arguments

object	An inla.mesh object
...	Other arguments passed to specific methods
col	Colour for data points
lwd	Line width
linecol	The colour for the mesh edges
size	size Size of data points

Examples

## Not run: 
library(INLA)
m = 100
points = matrix(runif(m*2),m,2)
mesh = inla.mesh.create.helper(
  points=points,
  cutoff=0.05,
  offset=c(0.1,0.4),
  max.edge=c(0.05,0.5) )

autoplot(mesh)
p <- autoplot(mesh)

# As a ggplot2 object, the plot can be altered.
p + theme_dark()

# The size and colour of all objects can be controlled.
#   The order of the values is 
#   1: data points
#   2: edges
#   3: outer domain
#   4: inner domain
#   5: non data vertices
p + scale_colour_manual(values = c('red', 'grey', 'darkblue', 'steelblue', 'yellow'))

# The name of the variable that defines the different objects is 'type'
p + facet_grid(. ~ type)

# Plot projections with ggalt

library(ggalt)
p + ggalt::coord_proj("+proj=wintri")

## End(Not run)
