Ok. Can somebody with write privileges in bugzilla add the bug report? I
can also do this myself, if somebody with the required privileges can
create a user for me.

And if you are after shared-memory parallelism, you can try the 'Rdsm'
package: https://cran.r-project.org/package=Rdsm

In particular stdin() works in an interactive session but not when R -f
/ Rscript is used, since it does not wait for the user to input anything:

Environments and parallel processing
While using parallelization R seems to clone all environments (that are normally passed by reference) that are returned from a child process. In particular, consider the following example:
library(parallel)
env1 <- new.env()
envs2 <- lapply(1:4, function(x) env1)
cl<-makeCluster(2, type="FORK")
envs3 <- parLapply(cl, 1:4, function(x) env1)
envs4 <- parLapply(cl, 1:4,

Bias in R's random integers?
Not sure what should happen theoretically for the code in vseq.c, but
I see the same pattern with the R generators I tried (default,
Super-Duper, and L'Ecuyer) and with with bash $RANDOM using
N <- 10000
X1 <- replicate(N, as.integer(system("bash -c 'echo $RANDOM'", intern = TRUE)))
X2 <- replicate(N, as.integer(system("bash -c 'echo $RANDOM'",

Status of R_unif_index
Dear List,
section "6.3 Random number generation" of WRE [1] lists unif_rand(),
norm_rand() and exp_rand() as the interface to R's RNG. Now
R_ext/Random.h also has
double R_unif_index(double);
Can this be also treated as an official API function that may be called
from a package?
Thanks

Surprising results from INTEGER_GET_REGION with ALTREP object
Dear Listmembers,
wanting to learn more about ALTREP I wrote the following function to
extract a subsequence from an integer vector:
#include <Rinternals.h>
SEXP integer_get_region(SEXP _x, SEXP _i, SEXP _n) {
int i = INTEGER(_i)[0];
int n = INTEGER(_n)[0];
SEXP result = PROTECT(Rf_allocVector(INTSXP, n));

nlminb with constraints failing on some platforms
I've noticed unstable behavior of nlminb on some Linux systems. The problem can be reproduced by compiling R-3.5.2 using gcc-8.2 and running the following snippet:
f <- function(x) sum( log(diff(x)^2+.01) + (x[1]-1)^2 )
opt <- nlminb(rep(0, 10), f, lower=-1, upper=3)
xhat <- rep(1, 10)
abs( opt$objective - f(xhat) ) < 1e-4 ## Must be TRUE

Bias in R's random integers?
A quick point of order here: arguing with Duncan in this forum is
helpful to expose ideas, but probably neither side will convince the
other; eventually, if you want this adopted in core R, you'll need to
convince an R-core member to pursue this fix.
In the meantime, a good, well-tested implementation in a
user-contributed package (presumably written in C for speed) would be
