spaghetti: Draw spaghetti lines of trajectories.

Description

Using the trajectories given by x and y, spaghetti draws lines along each trajectory. The lines are colored using the passed in function col. x and y should be 2d matrices with particles along the first axis and time along the second axis.

Usage

spaghetti(x, y, col=heat.colors, add=F, lwd=1)

Arguments

x

x locations.

y

y locations.

col

A function that takes 1 argument n, and returns n colors that will be used to color the trajectories.

add

Should the lines be added to the current plot.

lwd

Line width. See par

Examples

# Create a set of random trajectories.
x <- matrix(rnorm(10000), 100)
y <- matrix(rnorm(10000), 100)
for(i in seq(100)) {
  x[i,] <- cumsum(x[i,])
  y[i,] <- cumsum(y[i,])
}
spaghetti(x, y, col=jet.colors)
