Using unicode character for 'middle dot' in options(OutDec)
When drawing a graph, I'd like the unicode character 'middle dot'
(or something else similar to \cdot in latex) to be used when writing
numbers. Something like the following works for me:
x <- 1:10
y <- runif(length(x))
par(las=1, bty='n')
plot(x,y, ylim=c(0,1), yaxt='n')
p <- pretty(y)
axis(2, at=p, labels=format(p, decimal.mark="\u00B7"))

bug with OutDec option and deferred_string altrep object
While implementing R's new 'altrep' functionality in the TERR engine,
I discovered a bug in R's 'deferred_string' altrep object: it is not
using the correct value of the 'OutDec' option when it expands a
deferred_string. See the following example:
R 3.5.1: (same results in R 3.6.0 devel engine built 10/5)
> options(scipen=0, OutDec=".")

Thanks for the report. The approach you outlines below should work --
I'll look into it.
Best,

numerics from a factor
A problem has been pointed out by a French user of the survival package and I'm looking
for a pointer.

A year or two ago some test cases that broke survfit were presented to me. The heart of
the problem was numbers that were almost identical, where table(x) and unique(x) gave

comma as decimal separator in xtable
Hello,
How can I make xtable print a comma as decimal separator? Setting
the option OutDec isn't enough for xtable:
library(xtable)
options(OutDec = ",")
x <- c(1.1, 1.2, 1.3)
y <- c(2.3, 2.2, 2.1)
d <- data.frame(x, y)
d
print(xtable(d))
Thanks!

aligning axis labels in a colorkey from levelplot
R does a great job with the fine details regarding plots. e.g in the
following:
library(lattice)
y <- -4:4/10
xyplot(y~1, las=1)
the y axis is labelled with numbers -0.4, -0.2, 0.0, 0.2, 0.4 with the
numbers aligned on the decimal point.
How do I get the same behaviour in the colorkey of a levelplot? e.g.
levelplot(matrix(y,3,3))
the numbers in the colorkey seem left-aligned, and

as.numeric(levels(factor(x))) may be a decreasing sequence
Function factor() in the current development version (2009-05-22)
guarantees that levels are different character strings. However, they
may represent the same decimal number. The following example is derived
from a posting by Stavros Macrakis in thread "Match .3 in a sequence"
in March
nums <- 0.3 + 2e-16 * c(-2,-1,1,2)
f <- factor(nums)
levels(f)

Adding title to colorkey
A recent paper on visualisation (in Neuron, a leading neuroscience
journal) surveyed how well previous articles in this journal labelled their
graphs (e.g. axis labelling and describing their error bars). Of
particular interest is that (only) 40% of plots labelled what their
colorkey was showing (variable and units).
The paper is at http://dx.doi.org/10.1016/j.neuron.2012.05.001

Fontconfig warning with X11() on MAC OS X 10.4
I posted previously about problems with X11() on my MAC using R 2.8.1 .

However, I receive the following warnings with any plotting command using
the default X11 settings.

Way to handle variable length and numbers of columns using read.table(...)
I've got read.table to successfully read in my table of three columns. Most of the time I will have a set number of rows, but sometime that will be variable and sometimes there will be only be two variables in one row, e.g.
Time Loc1 Loc2
1 22.33 44.55
2 66.77 88.99
3 222.33344.55
4 66.77 88.99
Is there any way to have read.table handle (1) a variable number of rows, and (2) sometime there

bug in `pmatch' (error with too long 'choices')?

yields 'white', but
match.arg("whit", colors())
yields:
`Error in match.arg("whit", colors()) :

bug (PR#13570)
<<insert bug report here>>
This is a CRITICAL bug!!! I have verified it in R 2.8.1 for mac and
for windows. The problem is with loess degree=0 smoothing. For
example, try the following:
x <- 1:100
y <- rnorm(100)
plot(x, y)
lines(predict(loess(y ~ x, degree=0, span=0.5)))
This is obviously wrong.

'R CMD check' fails with "evaluation nested too deeply: infinite recursion"
I get the error
Error : evaluation nested too deeply: infinite recursion / options(expressions=)?

on one of my packages. The reason seems to be that this package is
mutually dependent on another one (i.e. the DESCRIPTION files of package

Bugzilla activity?
Hi!
I was wondering whether anybody was looking at the bugs on Bugzilla. I'm
asking because I've seen bugs tackled on the mailing list quite quickly,
but two fully reproducible reports I've filed on Bugzilla haven't
triggered any reaction in several weeks (for the older one).

Unexpected mfrow, layout behavior (pdf still has multiple pages)
My goal is to create a graph with one column and three rows into a
single graphic. The mfrow, mfcol, and layout functions all have the
same effect: three graphs are produced in a single pdf file, having
one graph per page. This is not what I want (I didn't want multiple
pages). Just before I sent this post, I was able to generate the

One of the examples in Rscript.Rd seems mis-formatted, in that the

Both Rscript.Rd in R 2.5.0 and the version at:
