clplot {plotrix}

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’.

Value

nil
