[R] calculating arc length using R?

[Giovanni Petris]

It seems you want to integrate a function. Try

?integrate

You can do the math yourself if the function is simple, like sin(x). 
Otherwise I suspect you could combine integrate with `deriv', although
you will slow down the calculations somehow (just a guess).
