Hello.
There was a lot of discussion in March about the difficulties in
having Rtools use a more recent version of GCC than 4.6.3. May we know
if there has been any progress since then, or has dveleopment/testing
been put on hold for the time being?
Thank you,

Here's a simple example:
library(scales)
library(methods)
MyRange <- setRefClass("MyRange", contains = "DiscreteRange")
a_range <- MyRange()
a_r
I understand Hadley's point; it's a consequence of the modification of the
environment of the ref. class methods.
Good point, but it seems we can make that an option (there are advantages to it
of code quality and ease of writing, when it works);
Let's discuss possibilities, off-list until thin
I can provide a little background on why particular choices were made for
R6. Generally speaking, speed is a primary consideration in making
decisions about the design of R6. The basic structure of R6 classes is
actually not so different from reference classes: an R6 object is an
environment. But m
