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

Im lost i want to post on the other forum...the address was something like... http://old.nabble.com/R ...to get help with using R but i kept getting redirected to this one (http://n4.nabble.com), and when i tried to post a querie it made me sign up so i thought the forum was changing or being updated or something like that. When i type in http://old.nabble.com/ then click on R I get redirected to... http://n4.nabble.com/R-f789695.html ...?????????????? Im sorta lost i just want help with my R code nothing else as im new to R. [[alternative HTML version deleted]]

So, go ahead and post your questions concerning your R code. You are in the right place. Hope this is helpful, Dan Daniel Nordlund Bothell, WA USA
