How to Sum a Function with a Free Parameter in R?

[aymer]

Hey everyone,

This is for someone who has used R. Please tell me how can we sum a function with a free parameter in R.
I used the normal command f=function(n) sum(body of function containing n)
it does not show any warnings till here, but when I plot this sum vs n (which i now define as a sequence, n=seq(-1.2,0.8)), it shows that the two quantities have differing lengths.

How can this be if my sum is a function of n?
Did I define the sum incorrectly?

Please help

You talk about the "command" "f=function(n) sum(body of function containing n)" so apparently you are using some computer algebra system. But we cannot help you without know which system (Maple, Mathematica, ...) you are using!
