Hi,
You will find some pieces of information about the way to handle such things at:

Programming with references
Note that you will have to download and install the package developped by the author, Henrik Bengtsson

Hi, is there a way to reference to a data object without copying it?
For example I have a huge matrix called dist and I want two objects obj1 and obj2 to have a memeber dist that points to the matrix, but I don't want, for memory reasons, to copy the matrix twice.
As far as I understand the following code will generate three copies of my data:
dist <- some_code_that_generates_data obj1$dist <- dist obj2$dist <- dist
Thank you! Giampiero
