plotrix (version 3.8-2)

clplot: 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,...)

Value

nil
