Data Transfer

This document describes data transfer, in both directions, between R and Julia. The changes from the version of XRJulia described in Extending R are in the transfer of vectors and named lists. The main new features are:

• data transfer is now defined for all types of R vectors, including logical, raw and complex;

• for all atomic types, transfer now has two methods, one using the JSON-style form (for small data) and one using a version of binary transfer through a an intermediate file for larger data;

• named lists no longer use the JSON form, which Julia no longer allows;

• the function juliaOptions() has been added to allow specification of parameters for the Julia evaluator in the style of the options() function. The parameter largeObject can be used to set the corresponding field in an evaluator (by default the current evaluator).
