Jeff,
Nice writeup and promising idea. From the gimme numbers department:
- do you pass the R regression tests?
- what sort of speedups do you see on which type of benchmarks?
When you asked about benchmark code on Twitter, I shared the somewhat
well-known (but no R ...)
Hi,
I wanted to share with the mailing list members here details about the
project I've been working on:
https://github.com/jeffreyhorner/R-Array-Hash
This is a re-implementation of R's hashed environments, the global
variable cache, the global string cache and symbol table with
cache-conscious
Hi Aaron,
Thanks for catching this.
I favor enforcing names in 'assays'. Combining by position alone is too
dangerous. I'm thinking of the VCF class where the genome information is
stored in 'assays' and the fields are rarely in the same order.
Looks like we also need a more informative

I made sure that the implementation passed 99% of the tests, however
there were two that gave differing
Hi,
Has anyone in R core thought about providing hyper-dual numbers in R?
Hyper-dual (HD) numbers, invented by Jeffrey Fike at Stanford, are useful for
computing exact second-order derivatives (e.g., Hessian). HD numbers are
extensions of complex numbers. They are like quaternions and have 4
I realized I sent this response the first time from the wrong email, so I
don't believe it made it to the mailing list. Apologies if
you receive this twice.
In regards to using covr with RUnit tests, covr is not dependent on using
any particular testing framework it simply runs any commands
