.. similarly to embedding python when computing metrics
.. exactly the same semantics, although R isn't fussy
about whitespace.
.. and example metric might be:
{
value { %%R GC.result(19) %%; }
}
.. the interpreter is protected with a mutex which means
R programs will never run in multiple threads. This has
a performance penalty, but then using R for metrics is
likely to be rather specialised anyway.

About
GoldenCheetah is an open-source data analysis tool primarily written in C++ with Qt for cyclists and triathletes with support for training as well.
GoldenCheetah can connect with indoor trainers and cycling equipment such as cycling computers and power meters to import data.
