Error in documentation for ?legend
To whom it may concern:
The help page for ?legend refers to a `title.cex` parameter, which suggests that the function has such a parameter. As far as I can tell, though, it doesn't; here's an example:
> plot(1,1)
> legend("topright",pch=1, legend="something", title="my legend", title.cex=2)

be careful: using attach in R functions
Hi there,
I have just found that the ``attach'' function
can get you into trouble when called many times.
For example, you have a simulation routine called ``f()'',
in which you used ``attach'' and no corresponding ``detach''.
Then you call this function many times. You will find that
the system performance get slower and slower,
because you are making the R

Java/C interface with R
Hi,
I'm rarther curious if it is possible to interface C or Java GUIs with
the underlying R statistical engine. SPLUS has something like this in
S+SDK.

Error in documentation for ?legend
Right, that's my point. The help page mentions a `title.cex`, like I said; saying that `cex` sets the default `title.cex` sure implies to me (and presumably to the other people whose discussion I linked) that a `title.cex` parameter exists. Since no such parameter exists, this bit in the documentation is misleading (suggesting that there is a `title.cex` parameter which can be set, when there

question
Hi,
I have a problem with R, after an update:
this piece of code:
cat("creating resolver data frame\n");
dfG<-cbind(dfG,2^(RGN$G))
dfR<-cbind(dfR,2^(RGN$R))
suddenly, creates values to inf.
Is the syntax changed for the ^ symbol in the latest R downloadable version?
Kind regards, wilfred

lattice graphics and source()
Hi,
I am trying the lattice graphics in R. Let's say, such a little
experiment in file myprog.r:
f <- function(){
x <- 1:10
y <- x^2
xyplot(y ~ x)
}
f()
Then I run the program:
> source("myprog.r")
but nothing happens. Manully run f() at the command line:
> f()
then the figure is shown. This seems to be a bug only associated with
lattice graphics, the

I compiled R 1.1.0 source on SUN Sparc
solaric 2.5.1, using gcc 2.95.2.

the NEWS in this version said that there is a new

Sound card problem in acoustic echo cancellation
Then why ONE sound card have different capture and playback rate?
It must be ONE single physical clock generator which is used by both ADC and DAC
in the sound card, isn't it?
If you are a hardware engineer. Will you design two different physical clock for
ADC and DAC seperately?
What on earth causes this problem? Who knows its intrinsic real reason?
Isn't there any other solutions?

Edwin,
thank you for your effort, but I'm not sure I understand.
Are you describing a graph traversal problem? Is the data model stored
in a predecessor/successor fashion, which requires you to 'walk' the
graph in order to visit all nodes? (and what happens when you have
disjointed DFGs?).

Theil test help
Hello,
I have a series of questions that I hope will be simple to answer. Basically I would like a code to do the following so that I can compute the distribution free test for the slope of a postulated regression line (Theil test). As I am testing the null hypothesis that slope = 0 against the general alternative the slope does not equal 0, it should be pretty straight-forward.
I have a data

[LLVMdev] DFG of machine functions
Hi,
I am trying to generate the DFG of machine functions.
Initially, I added a pass to generate the DFG of LLVM IR functions. This
was based on the mail thread -
http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-September/025582.html. This
pass worked fine and I was able to generate DFG of LLVM IR functions.
Later, I ported the DFG pass code for machine functions. I ported the

how to fix the level-1 variances in lme()?
Dear all,
Edmond Ng (http://multilevel.ioe.ac.uk/softrev/reviewsplus.pdf) provides
an example to fit the mixed effects meta-analysis in Splus 6.2. The
syntax is:
lme(fixed=d~wks, data=meta, random=~1|study, weights=varFixed(~Vofd),
control=lmeControl(sigma=1))
where d is the effect size, study is the study number, Vofd is the
variance of the effect size and meta is the data frame.

[LLVMdev] DFG of machine functions
I tried debugging it and the issue seems to be in the implementation of
MachineInstrIterator.h and the way it interacts with GraphWriter.h
functions. I found this by replacing the ( template <> struct
GraphTraits<MCDFGraph<MachineFunction*> >) with a similar MCDFGraph based
template of CFG similar to the one in MachineFunction.h (similarly
replacing the DOTGraphTraits with the
