BATCH and tcltk
Hi R-hackers
I try to write a batch (in Windows, i have to use!) with
Rcmd BATCH D:\Test.R D:\Test.Rout and
Rterm.exe --no-restore --no-save < D:\Test.R > D:\Test.Rout.
In my file Test.R are any tk-codelines (like: Window1 <- tktoplevel(); ... tkbutton...).
It works not interactifly, what is written in Rcmd BATCH --help.
Exist there a way to do it all the same?
Please help...

Delete files from R
Hi,
I have a file: d:\foo.txt and want to delete this.
I tried:
system("del d:/foo.txt") works not
system("notepad d:/foo.txt") works
Is it possible that I can't delete files or do I have misunderstood something?
(del is a DOS-command. The "string works" under DOS "\")
Thanks a lot

Rcmd vs. Rterm.exe
Hi r-hackers,
What exactly is the difference in call r from a batch between this two ways:
Rterm.exe ...
Rcmd BATCH ... (I have to install perl first, I know)
I haven't found any documentation about the difference (readme, FAQs, ...).
I use rterm.exe, but is there a benefit in using rcmd?
Can you explain me that or give me a link?
Thanks
Thomas

Drawing dendrogram
Dear all,
I would like to draw a dendrogram and mark some parts/branches (by using "segments") including their labels. If I draw it without specifying the length of x axix, I am able to do that (as in My dendrogram 1 of the following codes). However, if I want to specify the x axix, I am not able to draw marking line (by using "segments") including labels (as in My dendrogram

PhD student reading list, suggestions wanted
I've got a PhD student starting this year.
She'll be working on data mining.
She has asked for a reading list while she's still in her home
country, which is a really good sign.
Her cosupervisor and I don't (think we) have any problem with
choosing things that are specifically about data mining, but
there are some statistical ideas (sampling, exploratory-vs-confirmatory,

how to plot density distribution with a arrow pointer?
Hi all,
for example:
> X<- rnorm(1000)
> X0 <- 0.899
I want to draw a density distribution plot with a arrow pointer
indicating the position of X0, meanwhile, giving out the p-value.
any functions?
Thanks very much.

Drawing sample from a circle
Hi, I would like to draw 10 uniformly distributed sample points from a circle with redius one and centered at (0,0). Is there any R function to do that?

'par mfrow' and not filling horizontally
Greetings, Folks.
I'd appreciate being shown the way out of this one!
I've been round the documentation in ever-drecreasing
circles, and along other paths, without stumbling on
the answer.
The background to the question can be exemplified by
the example (no graphics window open to start with):
set.seed(54321)
X0 <- rnorm(50) ; Y0 <- rnorm(50)

Evaluate function on a grid
I have a function in R^2, say
f <- function(x,y) { ...skipped }
I want to plot this function using contour, persp. wireframe, etc. I know
that the function has a global
minimum at (x0, y0)
The naive approach is to evaluate the function on the outer product of two
arrays, like this:
sx <- c(seq(-3, x0, len = 100), seq(x0, 3, len = 100)[-1])
sy <- c(seq(-3, y0, len = 100), seq(y0, 3,

suggest enhancement to segments and arrows to facilitate horizontal and vertical segments
I suggest a simple enhancement to segments() and arrows() to
facilitate drawing horizontal and vertical segments --
set default values for the second x and y arguments equal to the first set.
This is handy, especially when the expressions for coordinates are long.
Compare:
Segments:
< function (x0, y0, x1 = x0, y1 = y0, col = par("fg"), lty = par("lty"),

arrows: no vectors for "code" and "angle" parameters
I was teaching new R users to make some fun graphs. I had some arrows examples
worked up we came across a problem. The arrows function ignores 2nd
and following elements of vectors given as code an angle.
Would you please consider 1) allowing vectors for code and angle, or
2) returning an error or warning when user mistakenly supplies a
vector for those parameters? When code like this is

Trouble passing arrays to C code
Hello,
I'm having more trouble with interfacing with C code. I have a
function in C that will return the result of its computation as 3
arrays. The signature of the function is as follows:
void lorenz_run(double x0, double y0, double z0, double h, int steps,
double *res_x, double *res_y, double *res_z)
The function works, as I've tested it from within C itself and the
