Hi,
I have a simple set of two columns data (x,y) and I would like to find 
the equation which provides the best fit using R (without any 
preconceived idea about any polynomial or exponential or whatever 
function).
Any help please?
Thanks Rachid

Have you looked at

     library(modreg)
     help(smooth.spline)
?
