Could this be related to "SIGNIFICANT USER-VISIBLE CHANGES The default method for generating from a discrete uniform distribution (used in sample(), for instance) has been changed. This addresses the fact, pointed out by Ottoboni and Stark, that the previous method made sample() noticeably non-uniform on large populations. See PR#17494 for a discussion. The previous method can be requested

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

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

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

Ralf I don't doubt this is expected with the current implementation, I doubt the implementation is desirable. Suggesting to turn this to pbirthday(1e6, classes = 2^53) ## [1] 5.550956e-05 (which is still non-zero, but much less likely to cause confusion.)

Hi again, For what it is worth, we found out that MS Outlook on Citrix now and then opens thousands(17-18000) of references(filehandles) to the same PAB(Personal Address Book) files and then give up these references again after a while !? This was what made Samba chooke. We will now remove all PAB access from Outlook. Sorry for wasting Samba mailing list bandwidth ;-) Kind

Hello, I recently migrated all data and user accounts from our old Samba file server to a new (Samba 3.4.0 on Unbuntu 9.10) one. Everything is working fine except that there is one user whose SID is showing in the "Owner" column of Windows Explorer instead of the user name. It's not a big problem, but the user is uncomfortable with it and I'd like to know why it's

Hi, Our department has detected a bug in the implementation of the Kinderman-Ramage generator for normal random variates in version 1.7.0, which can be seen from the below R session. (Consecutive calls for chisq.test(...) always gives p-values very close to 0.) We have already encountered this bug in version 1.6.2 The error is in file R-1.7.0/src/nmath/snorm.c Here is a patch for this file to

The survexp function can fail when called from another function. The "why" of this has me baffled, however. Here is a simple test case, using a very stripped down version of survexp: survexp.test <- function(formula, data, weights, subset, na.action, rmap, times, cohort=TRUE, conditional=FALSE, ratetable=survexp.us, scale=1, npoints, se.fit,

Dear R people, In typing names of functions (built in or from a package) I often guess wrong, and have to look the name up. In other words, I don't understand the logic in naming functions (if there is any): - most names are plain, lower case: cos, plot, sapply, t, toupper, unserialize, (etc) - some are capitalized: Filter, Machine, Map, NCOL, RNGversion, T (etc) -

Hi, I think at first you have to do a net groupmap add all the well known Groups.

I am trying to replicate part of the function of the S-Plus terms.inner function. I don't need an entire model terms object but R expressions or character strings containing the innermost variable name given a vector of character strings or expressions. Here are some example inputs that each should result in the string or expression "x": x; x^2; g(x); h(g(x)); h(g(x^3));

There are 4 items I want to mention: 1. arsenal is now on github: https://github.com/eheinzen/arsenal 2. ~10 bugs have been fixed in the latest release. 3. Tired of subsetting data.frames and losing your labels? Try the new keep.labels

I think improvements in the RNG is a situation where backward compatibility is not really going to be lost, because people can specify the old generator, they just will not get it by default. My opinion is that the default needs to generally be the best option

Luke, I'm happy to help with this. Its great to see this get tackled (I've cc'ed Kelli Ottoboni who helped flag this issue). I can prepare a patch for the RNGkind related stuff and the doc update. As for ???, what are your (and others') thoughts about the possibility of a) a reproducibility API which takes either an R version (or maybe alternatively a date) and sets the RNGkind

In base R, there are lots of environment variables with either prefix 'R_' or '_R_', e.g. R_ENABLE_JIT and _R_RNG_VERSION_. I always considered R_* variables to be "public" and _R_*_ ones being "internal" but realized I don't have a reference for this. Is this true, or is there another reason? Is the difference between the two kinds documented anywhere?
