parRapply and parCapply return a list in corner cases
According to ?parCapply:
parRapply and parCapply always return a vector.
This appears not to be the case in the following minimal reproducible example:
> library(parallel)
> nslaves <- 2
> cl <- makeCluster(nslaves)
> X <- matrix(2,nrow=3,ncol=4)
> X <- rbind(c(1,1,0,1),X)
> tv <- parCapply(cl,X,FUN=function(x){

Under Windows, Rgui and Rterm crash if one tries to close the graphic device while identify or locator are running
minimal reproducible example
plot(1,1)
identify(1,1) # or locator()
now, trying to close the window by clicking on the cross of the upper
right corner causes Rgui (and Rterm) to crash.
I see the same behaviour on 2 different Windows PC (one with Win 8.1
and one with Win 10).
I did not see the problem in linux (see below)

Under Windows, Rgui and Rterm crash if one tries to close the graphic device while identify or locator are running
If of any help,
I can reproduce this (on Windows 7) back to at least R 3.0.3 but it's
not there in R 3.0.0. (I have *not* checked with R 3.0.1 and 3.0.2
which I don't have installed).

bug in plot.ts?
Dear all,
I think I have found a buglet in plot.ts
plot.ts(x=1,type="n") # correct: does not show the plot
plot.ts(x=1,y=1,type="n") # not correct: does show the plot
I did not investigate the problem in depth but it could be related to
the switch xy.labels, in fact
plot.ts(x=1,y=1,type="n",xy.labels=TRUE) # does show the plot

quantile(), IQR() and median() for factors
Dear all,
from the help page of quantile:
"x ??? numeric vectors whose sample quantiles are wanted. Missing
values are ignored."
from the help page of IQR:
"x ??? a numeric vector."
as a matter of facts it seems that both quantile() and IQR() do not
check for the presence of a numeric input.
See the following:
set.seed(11)
x <- rbinom(n=11,size=2,prob=.5)

That doesn't necessarily mean that 3.0.0 was fine. It's a segfault (I'd

Redefine NROW and NCOL to be compatible with nrow and ncol for S3 classes with own dim function?
Dear R-developers,
I am currently trying to develop a package with some customized
container classes and found an issue with the functions NROW and NCOL. I
guess that I can simply work around the problem by redefining these
functions in my own package (Yet, I do not know whether that will work
cleanly everywhere). Nevertheless, I thought that perhaps one might
think about to redefine these

Dear all,
it looks like that something is wrong with the

Also, I do not know if it is relevant but notice the dates of the

legend() in a multiple figure environment
Dear all,
there seems to be a problem with displayed legends when a multiple
figure environment is used, see the following example:
par(mfrow=c(1,2))
curve(dnorm,col=4,from=-4,to=4);
legend(-4,0.3,legend="curve",lty=1,col=4)
legend(-4,0.2,legend="curve",lty=1,col=4)
On my machines the first time the command legend() is issued the
legend box stretches over the curve.

(PR#12770) format() under Windows giv wrong resuts with
On Windows XP SP3

[1] "11:43:12 PM"
In any case, if there is a problem it is in Windows, not in R, since this
is an Windows service that is being called. So there is no evidence at
all of any bug in R here.

switch() called with just the EXPR argument causes R to hang (PR#14124)
Dear all,
switch() called with just the EXPR argument causes R to hang so that the
only way to stop it is to kill R.
Reproducible example:
> switch(EXPR="a")
the internal C subroutine behind switch is do_switch located in
R/src/main/builtin.c
For convenience I reproduce it below.
