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){

qf with infinite df
Dear all,
I found the following behaviour
> rf(5,Inf,Inf)
[1] 1 1 1 1 1
but
> qf(0.1,Inf,Inf)
[1] NaN
Warning messages:
1: In qf(0.1, Inf, Inf) : value out of range in 'lgamma'
2: In qf(p, df1, df2, lower.tail, log.p) : NaNs produced
incidentally,
> pf(1.00000000000001,Inf,Inf)
[1] 1
> pf(1.0000000000000001,Inf,Inf)
[1] 0.5
Is this the expected behaviour?
Thanks

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)

/bin/windows/base/rpatched.html page out of date
Dear all,
it looks like that something is wrong with the
/bin/windows/base/rpatched.html page as it seems pointing to the
2.8.1rc version.
Also, I do not know if it is relevant but notice the dates of the
following files on
ftp://ftp.stat.math.ethz.ch/Software/CRAN/bin/windows/base/

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.

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

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.

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).

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)

Bug in pacf -- Proposed patch
Dear all,
following the thread

regarding the bug in the partial autocorrelation function for
multivariate time series.
I have prepared a web page with patches and relevant information.

NROW and NCOL on NULL
Dear list,
I do not know what would be the 'correct' answer to the following but
I think that they should return the same value to avoid potential
problems and hard to debug errors.

typo in cov()? var() fails on NA in R 2.7.2 but not R 2.6.1
I recently started using R 2.7.2, and noticed a surprising change in
the behavior of var() on NA data:
R 2.6.1 (Patched), 2007-11-26, svn.rev 43541, x86_64-unknown-linux-gnu:

A question on R memory management in .Fortran() calls under Windows
Dear R community,
I have a question on how R manages memory allocation in .Fortran()
calls under Windows.
In brief, apparently, it is not possible to allocate large matrices
inside a Fortran subroutine
unless you pass them as arguments. If you do not act in this way
RGUI crashes with a stack overflow error and acting on memory through
vsize nsize ppsize and memory.limit does not help at all.

fix() changes the class of mts objects
Dear all,
it looks like fix() changes the class of mts objects, here is a reproducible
example (tested both on WinXP and Linux):
> x <- ts(cbind(1:5,1:5))
> x
Time Series:
Start = 1
End = 5
Frequency = 1
Series 1 Series 2
1 1 1
2 2 2
3 3 3
4 4 4

CCF and ACF
Dear all,
given two numeric vectors x and y, the ACF(x) at lag k is
cor(x(t),x(t+k)) while the CCF(x,y) at lag k is cor(x(t),y(t-k)). See
below for a simple example.

Rgui crash under Windows
Dear all,
I found the following on R 2.3.1. for Windows XPpro SP2, tested on 2 PCs
AMD 64 3700+, Ati 9700
AMD Athlon 2400+, Matrox G550
Do the following:
x <- as.matrix(0);
fix(x)
pasting a big chunk of data, for instance the one below, into a cell
of the editor will crash the RGui.
