I have been trying to write a function for the following problem:

Suppose I have three vectors a,b,c of different lengths:
e.g. a=c(a1,a2,a3,...) where a[i] form the basis of our function variables:

if we define a table for example:




                        and define the fn(x) <-function{..sum(argument)..}
                        where x<-c(a,b,c) so that we can maximise fn(x) as:

                        optim(...,fn,....). So in other words the problem
                        if to find optimal values for vectors a,b,c. I'm
                        not sure how to set this problem up as a function
                        in R. Any help would be much appreciated.

                        Regards
