[R] Add a rectangle behind a plot

2008-02-26 Thread Judith Flores
Hi there,

   I found one reference to add a reactangle behind a
plot using plot(...,add=T), I tried this but didn't
obtain the desired result.

If a I have the following code:

plot(x,y)
rect(xleft, ybottom, xright,ytop,col='green)

   The rectangle appear on top of the plot.

Any help will be greatly appreciated,

Judith

Just replot the points over it again:

points(x, y)

Also there is an example using lattice graphics in the Example
section of:

library(zoo)
?xyplot.zoo

That's what you asked for by plotting it second.  Try something like

plot(x, y, type=n)
rect(xleft, ybottom, xright,ytop,col='green')
points(x, y)

 Any help will be greatly appreciated,
