bendplot: Bend plots

In TaoTeProgramming: Illustrations from Tao Te Programming

Description

Random bend plots. Describing them is hard, seeing them is easy.

Usage

bendplot(num = 20000, xdelta = 0.1, ydelta = 0.2, 
   sd = 1, lwd = 2, color = "black", seed = NULL)
bendplotmultcol(num = 20000, xdelta = 0.1, ydelta = 0.2, 
   sd = 1, lwd = 2, color = colors(), cnum = 100, seed = NULL)
bend(num = 20000, xdelta = 100, ydelta = 200, sd = 1)

Arguments

num	number of data points
xdelta	horizontal scaling.
ydelta	vertical scaling
sd	standard deviation of normal deviates.
lwd	a single number giving the line width.
color	one or more colors.
seed	an integer giving the argument for set.seed.
cnum	an integer giving the number of colors to use.

Value

bend returns a two-column matrix.

Side effects

bendplot and bendplotmultcol create a plot on the current graphics device, and modify the random seed.

Examples

# one color
bendplot(xdelta=150, ydelta=150, 
    color=grep("green", colors(), value=TRUE), seed=2)
    
# multiple colors    
bendplotmultcol(xdelta=150, ydelta=150, 
    color=grep("green", colors(), value=TRUE), seed=2) 
    
bendplotmultcol(xdelta=100, ydelta=200, sd=.001, 
   color=grep("sienna", colors(), value=TRUE))
