percent sign in plot annotation
Hello,
I would like to annotate a graph with the expression 'alpha = 5%' (the
alpha should be displayed as the greek letter).
I tried
> text(1,1,expression(alpha == 5%))
which gives a syntax error.
escaping the percent sign (\%) or doubling (%%) does not help.
What do I do?
Thanks,
Martin Keller-Ressel

timezone problems
Hi,
Im using R 2.1.1 and running Code that previously worked (on R 2.1.0 I
believe) using the 'timeDate' function from the fCalendar package. The
code now throws an error:
Error in if (Sys.timezone() != "GMT") warning("Set timezone to GMT!")
However I have read the documentation of the fCalendar package and I have
set my system variable TZ to GMT.

Dial command problems
I am still testing Asterisk, but I am running in to a lot of problems.
I set up numerous extensions, but Asterisk is not performing to tasks
correctly. Here is an example.
exten => 231,1,Dial(Zap/g1/231|3)
exten => 231,2,Voicemail(u231)
exten => 231,3,Hangup
When I call in and enter extension 231, my call is routed to the correct
extension, but it just keeps ringing.

jitter-bug? problematic behaviour of the jitter function
Dear all,
i have noticed some strange behaviour in the ?jitter? function in R.
On the help page for jitter it is stated that
"The result, say r, is r <- x + runif(n, -a, a) where n <- length(x) and a is the amount argument (if specified).?
and
"If amount is NULL (default), we set a <- factor * d/5 where d is the smallest difference between adjacent unique (apart from fuzz) x

Underscore character in Rd files
Hi,
I'm trying to document a data frame in Rd format. The data frame contains
a variable called
'Health_Env'. When I create a template for the Rd file using 'prompt()'
the variable name is
included as-is and when I run R CMD CHECK I get a latex error because
latex considers '_' a special character (used for subscripts) which is
only allowed in math mode.

specifying exports for R CMD SHLIB
Hi,
How can I specify which functions should be exported when I build a
shared library with 'R CMD SHLIB foo.c'??
I tried putting a file named foo.def in the same directory with the
line 'EXPORTS' and the names of the functions to be exported, but the
file is deleted in the build process.
Any help is appreciated,

calling R from Perl
Hi,
I want to call R from Perl to generate plots to be displayed on a
webpage. What I found out so far is that there is a package called
RSPerl on www.omegahat.org which should do what I need. However in
the description it says it has been tested with R 1.3.* the latest.
I'm using R 1.8.0 right now so the package seems rather unmaintained.
It is not easy for me to just install it and see

readline/history size (PR#211)
Full_Name: Russell Senior
Version: 0.64.0
OS: linux-2.2.x
Submission from: (NULL) (198.107.133.11)
It appears that the GNU readline history size is limited to 50 entries. This
is apparently occurring because R is not bothering to override the readline
default value (from readline-4.0):
./history.c:59:#define DEFAULT_HISTORY_GROW_SIZE 50
It appears that it ought to be possible to override

RGui: windows-record and command history
a) How can I set the recording of all windows()-history forever to
"true"? I want something like windows(record = TRUE) but not just for
the window that opens then, but for all windows I will open ever.

visualizing a list of probabilities
Hi,
I'm using nnet to work on a 2 class classification problem. The result
of my code is data.frame of true class, predicted class and associated
probability.
One way of summarizing the data is by a confusion matrix. However are
there any graphical ways I could represent the data - specifically, I'd
like to show the probabilities associated with each member of my
prediction set?

[R] jitter-bug? problematic behaviour of the jitter function
Hello,
R 4.0.2 on Ubuntu 20.04, sessionInfo at end.
This came up in r-help, I'm answering to the OP and also posting to
r-devel since I believe it is more appropriate there.
I can confirm this. The original instructions are the first and the
last, but even with smaller numbers the error shows up.

Colouring hclust() trees
I have a data set with 6 variables and 251 cases.
The people who supplied me with this data set believe that it falls
naturally into three groups, and have given me a rule for determining
group number from these 6 variables.
If I do
scaled.stuff <- scale(stuff, TRUE, c(...the design ranges...))
stuff.dist <- dist(scaled.stuff)
stuff.hc <- hclust(stuff.dist)

Sys.timzone() returns NA - problem caused by as.POSIXlt? (PR#8003)
This is not a bug in R: the documentation does say the result is
OS-specific.
`GMT' is a not a proper timezone on Windows, so NA is a valid answer.
(Windows seems to use GMT to refer to the timezone of the UK, e.g.
> Sys.time()
[1] "2005-07-11 07:49:56 GMT Daylight Time"
> Sys.timezone()
[1] "GMT Daylight Time"
although I am in British Summer Time not GMT.)
