RArray shallow copy constructor? #31

Open randy3k opened 10 years ago

randy3k commented 10 years ago

Currently, It seems that v_r = RArray{Float64, 1}(v) deep copy the content of v to v_r. For the sake of speed and memory storage, there should be methods to construct v_r which points to the same memory of v.

It has been on my rpy2 for quite a long time but:

this is easier said than done
there is a workaround: create the array in R and then expose it to Julia does work without copy

I am not saying that it will not happen, just that I am unsure about when it will (pull requests helping with it would be reviewed attentively though)

perhaps, it is limited by the memory management of R.
