Plot method for neighborhoodWalking().

Description

Plot method for neighborhoodWalking().

Usage

## S3 method for class 'walking'
plot(x, type = "area.points", add = FALSE,
  tsp.method = "repetitive_nn", path.width = 2, alpha.level = 0.75,
  polygon.type = "solid", polygon.col = NULL, polygon.lwd = 2, ...)

Arguments

x	An object of class "walking" created by neighborhoodWalking().
type	Character. Type of expected plot: "roads", "area.points" or "area.polygons". Valid only when case.set = "expected".
add	Logical. Add graphic to plot.
tsp.method	Character. Traveling salesperson problem algorithm.
path.width	Numeric. Set width of paths.
alpha.level	Numeric. Alpha level transparency for area plot: a value in [0, 1].
polygon.type	Character. "border" or "solid".
polygon.col	Character.
polygon.lwd	Numeric.
...	Additional plotting parameters.

Value

A base R plot.

Note

When plotting area graphs with simulated data (i.e., case.set = "expected"), there may be discrepancies between observed cases and expected neighborhoods, particularly between neighborhoods. type = "roads" inspired by Shiode et. al. (2015).
