Plot lines with colors determined by values.

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.

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.

Value

nil
