R help - Sep 2008 - Interpolation Function f(y)

Hello friends!!!

I have a list of values called y.
The list is y=c(221.0, 212.0, 206.0, 202.7, 198.4, 195.1, 192.2, 189.7,
187.6, 185.8);
y is f(x) and x=c(10,20,30,40,50,60,70,80,90,100). 

I only have x and y. I don?t know f(x). I would like interpolate f(x) to
obtain other values as f(15), f(25), f(35) and if it was possible obtain
f(110), f(120).

is there any function that allow me obtain this values??

Thank you very much, Luismi

I think that you can use the splinefun function:

f <- splinefun(x, y)

f(15)
