bias issue in sample() (PR 17494)
Gabe
As mentioned on Twitter, I think the following behavior should be fixed
as part of the upcoming changes:
R.version.string
## [1] "R Under development (unstable) (2019-02-25 r76160)"
.Machine$double.digits
## [1] 53
set.seed(123)
RNGkind()
## [1] "Mersenne-Twister" "Inversion"??????? "Rejection"
length(table(runif(1e6)))
## [1] 999863
I don't expect any collisions when using Mersenne-Twister to generate a
million floating point values....

bias issue in sample() (PR 17494)
Before the next release we really should to sort out the bias issue in
sample() reported by Ottoboni and Stark in
https://www.stat.berkeley.edu/~stark/Preprints/r-random-issues.pdf and
filed aa a bug report by Duncan Murdoch at
https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17494.
Here are two examples of bad behavior through current R-devel:
set.seed(123)
m <- (2/5) * 2^32

Development version of R fails tests and is not installed
G'day all,
I have daily scripts running to install the patched version of the
current R version and the development version of R on my linux box
(Ubuntu 18.04.2 LTS).
The last development version that was successfully compiled and
installed was "R Under development (unstable) (2019-02-25 r76159)" on
26 February. Since then the script always fails as a regression test
seems to
