I am running a small simulation, and getting very different run times when
I use different versions of R.
Two set-ups using the same machine (MacBook Pro 2013 vintage)
1. R version 3.1.3 running on system OS X 10.9.5
> system.time(source("simulationR-R.R"))
user system elapsed
3.890 0.061 3.965
Compared to
2. R version 3.5.1 running on system OS X 10.12.6
> system.time(source("simulationR-R.R"))
user system elapsed
277.924 2.087 280.841
The source code is identical. This is a pretty big difference running the
same code on the same hardware.
Before submitting the code, is this a known issue?
