clplot: Plot lines with colors determined by values.

In plotrix/plotrix: Various Plotting Functions

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
