Re: [R] reference to objects
Thanks for your answer, Yes, that will create two copies. What is it you want to do with the data? Do you want the capability of both of them changing the data? What type of processing are you going to do? The data should be read only (and all the objects share the same data values). One way is to store the 'name' of the object in the location and then use 'get/assign' to reference the data: obj1$dist - 'dist' obj2$dist - 'dist' my.sum - sum(get(obj1$data)) assign(obj1$data, new.values) The problem with this solution is that I would like to use those objects with already existing libraries, and thus I cannot choose how the data is read. To explain better, I look for a way to reference to the data that is transparent to the application. In C this would be done by assigning the pointer to the data structure, for example if dist is a C structure and obj1/2 contain a pointer called dist to that kind of structure, I would do: obj1-dist = dist; obj2-dist = dist; and then the rest of the code would not even know if obj1-dist is shared among different objects Thanks again, Giampiero __ James HoltmanWhat is the problem you are trying to solve?
