TableGen customized node with mayStore attribute is deleted if there is no use
Hi,
I define a customized node with customized type. The job of this customized
node is to move a value from one register class to another class. I find
that if there is no use of the destination register, this node will be
deleted from SDAG. For some reasons, I want to keep this node. So I attach
mayStore attribute to this node and I hope it will not be deleted. However,
it does not work like I

puzzled by math on date-time objects
Hi,
I don't understand the following. When I create a small artificial set
of date information in class POSIXct, I can calculate the mean and the
median:
a = as.POSIXct(Sys.time())
a = a + 60*0:10; a

R 2.5.1 - Rscript through tee
Hi, people.
I met a little problem for which someone might have a solution. Let's
say I have an executable file (named "pp.R") with this contents:
#!/usr/bin/Rscript
options(echo=TRUE)
a <- 1
Sys.sleep(3)
a <- 2
If I execute "./pp.R" at the shell prompt, the output shows the timely
progress of the script as expected. If I use "./pp.R | tee

Correction to ?alist (PR#8904)
Hi, people. ?alist says:
'alist' is like 'list', except in the handling of tagged arguments
with no value.
As written, this description is misleading. For example:
> list(e=3+5)
$e
[1] 8
> alist(e=3+5)
$e
3 + 5
We are not in the situation of tagged arguments with no value, and then,
clearly, 'list' and 'alist' behave

Small encoding question
Dear developeRs,
Compilation of the latest version (0.9-5) of my actuar package fails
with r-release MacOS_X ix86 on CRAN; see

All errors come from accented letters in comments in latin-1 encoded
files (except hierarc.R which is in UTF-8, my bad). Encoding is
declared as latin-1 in DESCRIPTION.

Truncated labels in hist (PR#8864)
Hi, people. Executing the following command:
hist(rpois(100,5), labels=TRUE)
yields a graphic in which some labels are truncated (on an X11 device).
The truncated labels are those over the highest bars. The hist function
should ideally manage enough room for the labels, automatically.
(Specifying ylim solves my problem, but yet, hist could be frienlier.)

having problems re-ordering a dataframe
Dear R users,
I need to reorder a dataframe using 3 variables for the determine the
sorting order.
When I create a simple dataframe to test the method, things work as I
expected:
a1 <- rep(1:10, each=8)
a2 <- rep(rep(1:2, each=4), 10)
a3 <- rep(c(1:4),20)
(a <- data.frame(a1, a2, a3))
for each combination of a1 and a2, a3 is increasing
t <- order(a$a1, a$a2, rev(a$a3))

Spurious output white line in R script (PR#8631)
I noticed that R scripts produce a spurious white line after output.
For example, the following shell script,

EOF
when made executable under the name ``hello`` along the search path, behaves
like this:

Small memory leak in plot on OS X (PR#11170)

Difficulty with qqline in logarithmic context
Hi, R friends. I had some difficulty with the following code:
qqnorm(freq, log='y')
qqline(freq)
as the line drawn was seemingly random. The exact data I used appears
below. After wandering a bit within the source code for "abline",
I figured out I should rather write:
qqnorm(freq, log='y')
par(ylog=FALSE)
qqline(log10(freq))
par(ylog=TRUE)

In any other case, the 'x' argument is coerced to a vector and

I'm trying to build a customized backend and I need to lower the formal
arguments like this:
There are several specific registers just for storing formal arguments. And
also there are several general purpose registers for computation. If there
is an instruction which uses parameters, I should first use a move

Navigating a grid.
Greetings
I am trying to make a multiple panel plot from a tool (genoPlotR) that
is layered on grid. My code and session info are below. When I execute
the code, I get a single plot in the center of the graphics page. I
have tried various pop/push/down/seekViewport commands at the end of
the plotpush method. There must be something I'm missing in the
documentation, I believe what I
