how to smooth a line in a graph

Hi R-users,

I have a line graph made by plot(). The line is very similar to
hyperbola, and consists of 5 points. How can I make it look smooth?

Thanks,

Rado

x <- c(1,2,3,4,5)
y <- c(5,2,1,.5,.2)
plot(x,y)
lines(spline(x,y, 100))
See ?spline

Hope that helps.

You may be interested in spline().  For example:

x <- 1:5
y <- c(1,3,4, 2.5,2)
plot(x, y)
sp <- spline(x, y, n = 50)
lines(sp)
