ink1">ink1">Hi all,

I'm working with some huge array in R and I need to load several ones to apply some functions that requires to have all my arrays values for each cell...

To make it possible, I would like to load only a part (for example 100 cells) of all my arrays, apply my function, delete all cells loaded, loaded following cells and so on.

Is it possible to unserialize (or load) only a defined part of an R array ? Do you know some tools that might help me?

Finally, I did lot of research to find the way array (and all other R object) are serialized into binary object, but I found nothing explaining really algorithms involved. If someone has some information on this topic, I'm interesting in.

Hoping my request is understandable,

All the best,

Damien.G
