Draw lines with sawteeth on side — sawteeth • rgplates

Function used for plotting subduction lines

Usage

sawteeth(
  x,
  left,
  cex = 1,
  shape = 1,
  splineshape = -0.5,
  col = "black",
  lwd = 1,
  ...
)

Arguments

x: (numeric) Two dimensional matrix of coordinates (x and y) columns.
left: (logical) Switch indicating whether to put the teeth on the left- or right-hand side.
cex: (numeric) Standard scaling argument, controls the size and number of sawteeth. Defaults are based on plot parameters (cxy), different device dimensions will lead to differently sized triangles.
shape: (numeric) Proportion of tooth height to its base.
splineshape: (numeric) Shape parameter of xspline (called twice!).
col: (numeric) The color of the teeth and the lines.
lwd: (numeric) The width of the line.
...: Additional arguments passed to polygon.

Value

The function has no return value.

Examples

# define points
x <- c(0.42, 1.90, 2.06, 1.28, 1.01, 1.05, 1.34, 2.14,
  4.25, 6.69, 7.96, 8.88, 9.35, 9.41, 8.84)

y <- c(1.06, 0.86, 1.91, 2.90, 4.25, 5.52, 6.81, 8.03,
  9.03, 9.25, 9.30, 8.88, 8.36, 7.00, 6.50)

# visualize the line with a sawteeth
plot(x, y, xlim=c(0,10), ylim=c(0, 10))

sawteeth(cbind(x,y), left=TRUE, col="#99000077")
sawteeth(cbind(x,y), left=TRUE, col="black", shape=0.5)


# use combination of cex and shape to control the size triangles
plot(x, y, xlim=c(0,10), ylim=c(0, 10))
sawteeth(cbind(x,y), left=TRUE, col="#99000077", cex=0.5, shape=3)
