In mbtyers/riverdist: River Network Distance Computation and Applications

Plotting a River Network

Description

S3 plotting method for the rivernetwork-class. Produces a map of all river segments of a river network object.

Usage

## S3 method for class 'rivernetwork'
plot(
  x,
  segmentnum = TRUE,
  offset = TRUE,
  lwd = 1,
  cex = 0.6,
  scale = TRUE,
  color = TRUE,
  empty = FALSE,
  linecol = 1,
  xlab = "",
  ylab = "",
  ...
)

Arguments

x	The river network object to plot
segmentnum	Whether or not to plot segment numbers (defaults to TRUE)
offset	Whether to offset segment numbers from lines (defaults to TRUE)
lwd	Line width
cex	Global character expansion factor for plotting
scale	Whether or not to give x- and y-axes the same scale
color	How to differentiate segments. If color==TRUE (default), segments will be drawn in solid lines with differing colors. If color==FALSE, segments will be drawn in the same color with differing line types.
empty	Creates an empty plot if set to TRUE. Suppresses differentiation by line type if color==FALSE, and suppresses segment number labels. Defaults to FALSE.
linecol	Line color to use if empty is TRUE or color is FALSE. Defaults to black.
xlab	Label for X-axis (defaults to "")
ylab	Label for Y-axis (defaults to "")
...	Additional plotting arguments (see par)

Note

This function is intended to provide basic visual checks for the user, not for any real mapping.
