Re: [R] Highlight overlapping area between two curves

2007-03-13 Thread Bojanowski, M.J. \(Michal\)
If PDF is OK, you can use the 'alpha' argument in colors, i.e.:

pdf( file.pdf)
p - seq(0.2,1.4,0.01)
x1 - dnorm(p, 0.70, 0.12)
x2 - dnorm(p, 0.90, 0.12)
plot(range(p), range(x1,x2), type=n)
polygon(p, x1, col = rgb(1,0,0, .5),lwd=4, lty=2)
polygon(p, x2, col = rgb(0,0,1, .5),lwd=4)
dev.off()
 

hth,
Michal

Subject: [R] Highlight overlapping area between two curves

Dear R helpers,
I have a graph as following; I would like to highlight the overlapping
area between the two curves. Do you know how to do this?
Thank you in advance for your help.
Nguyen

###START
x1 - rnorm(1, 0.70,0.12)
x2 - rnorm(1, 0.90,0.12)

d1 - density(x1)
d2 - density(x2)

plot(range(d1$x,d2$x), range(d1$y, d2$y), type = n,
 xlab = X value, ylab = Probability Density )

lines(d1, col = red,lwd=4, lty=2)
lines(d2, col = blue,lwd=4)

##END CODE

Perhaps not exactly what you wanted, but it might give you some ideas:

p - seq(0.2,1.4,0.01)
x1 - dnorm(p, 0.70, 0.12)
x2 - dnorm(p, 0.90, 0.12)
plot(range(p), range(x1,x2), type=n)
lines(p, x1, col = red,lwd=4, lty=2)
lines(p, x2, col = blue,lwd=4)
polygon(c(p,p[1]),c(pmin(x1,x2),0), col=grey)
