R help - Sep 2009 - Way to iteratively change line color and line style

I would like to have a way to automatically change the line color and line
style.

Below is an example of the items I am plotting.  I've contemplated coming up
with a list of desired colors and styles, but I am hoping there is an automated
way for this to be accomplished as the number of lines I will be adding to a
plot will be changing over time.

Thanks again for any insights and feedback.


plot(1,1, xlim=c(1000,4000), ylim=c(100000,800000), col=0, 
    xlab=c("Sq. Footage"), ylab=c("Cost ($)"))

square_footage_values<-c(1000:4000)
initial_val<-300
    
cost_per_square_footage_vals<-seq(from=100, to=200, by=10)
for(ii in 1:length(cost_per_square_footage_vals))
{
	lines(square_footage_values,
cost_per_square_footage_vals[ii]*square_footage_values)
}

Hi,

For auto-generating colors, try ?rainbow

Not sure about what you can do about alternating the line style ...
