clplot {plotrix}R Documentation

Plot lines with colors determined by values.

Description

clplot displays a plot of lines for which the colors are dependent upon the x and y values. clplot is similar to color.scale.lines except that while the latter calculates a color for each unique value, clplot assigns colors to groups of values within the cutpoints defined by levels.

Usage

 clplot(x,y,ylab=deparse(substitute(y)),xlab=deparse(substitute(x)),
  levels=seq(min(y)+(max(y)-min(y))/5,max(y)-(max(y)-min(y))/5,length.out=4),
  cols=c("black","blue","green","orange","red"),lty=1,showcuts=FALSE,...)

Arguments

x,y numeric data vectors.
ylab,xlab Labels for the X and Y axes.
levels Cut points to assign colors to the values of x and y.
cols The colors to be assigned.
lty The line type.
showcuts Whether to show the positions of the cut points.
... additional arguments passed to plot or lines.
