Generating a PostScript graphics under Windows
Hi,
I'am trying to generate a PS Graphic under Windows with a fixed location via
postscript(file="C:\\test.ps")
But I always become the error:
unable to start device PostScript
can not open 'postscript' file argument 'c:\test.ps'
There must be a very simple thing, that I make wrong.
Thanks in advance

legend: interplay between title and y.intersp
Hi,
I think you are right, legend cannot do it. I have now created my own
legend function where I changed only one line and now it works the way I
want it to. But I'm not sure if that might not have other side effects.
I have the impression that the legend and the title start at the same
y-position (try y.intersp=0). Only if y.intersp is big enough, then it
leads to a non-overlap of

Matrix oriented computing
Hi,
I want to compute the quantiles of Chi^2 distributions with different
degrees of freedom like
x<-cbind(0.005, 0.010, 0.025, 0.05, 0.1, 0.5, 0.9, 0.95, 0.975, 0.99, 0.995)
df<-rbind(1:100)
m<-qchisq(x,df)
and hoped to get back a length(df) times length(x) matrix with the
quantiles. Since this does not work, I use
x<-c(0.005, 0.010, 0.025, 0.05, 0.1, 0.5, 0.9, 0.95, 0.975,

playwith error message
Hi,
I'am using the playwith library to write my own small GUI application.
But I get the following error under Windows and Linux (Ubuntu):

Under linux my R program simply continues, but under Windows it stops.

legend: interplay between title and y.intersp
Set the legend position explicitly with x and y values and add xpd = TRUE
to the legend call to clip the plot to the figure region and not the plot
region (the default). Something like this (you may have to fool around with
y.intersp, etc. to allow enough space between the legend lines):
plot(c(0,1), c(0,1), type="n")
legend(x = .4, y = 1.25, legend=c("", "",

gmp::bigq vs. MASS::fractions

has someone experience which routine should be used for creating

reticulate + virtual environments
Hi,
I am using reticulate and a virtual environment (not conda) to run
Python scripts from RStudio. However, when I try to use my own
(existing) virtual environment, reticulate does not use it. If I run my
scripts, the installed modules (e.g., py_install("pandas",
"mmstat4.hu.data")) are not found. I believe this happens because
reticulate is using r-reticulate instead of

Have you tried https://rstudio.github.io/reticulate/ ?
Generally speaking, complex nonstandard package specific questions
such as yours rarely get a reply here -- there are 20,000+ packages
(and counting) after all! As reticulate was created by and integrated
with RStudio/Posit, I would think their site and help resources might
be a better venue. Of course, if you don't use RStudio, you may

Dynamically create a (convenience) function in a package
If you don't know the name of the attributes in advance, how can you know
the function name to be able to call it? This seems like a very flawed
approach.
Also, I would discourage the use of eval(parse(text = )), it's almost
always not the right way to do what you want to do. In your case,
eval(bquote(function(x) attr(x, .(n))))
would be better.

Palettes {grDevices} - wrong number of colors returned?
Hi,
I would have expected that I get always 3 colors as result which is not
true:
hcl.colors(3, alpha=c(0, 0.5, 1)) # 3 colors
rainbow(3, alpha=c(0, 0.5, 1)) # 3 colors
heat.colors(3, alpha=c(0, 0.5, 1)) # 3 colors
terrain.colors(3, alpha=c(0, 0.5, 1)) # 6 colors

Syntax highlighting
Hi,
I would like know if there are any plans for some "standardized" syntax
highlighting of R code?
* Currently I'm using minted for my LaTeX slides with pygmentize and I
do not know what scheme is used for highlighting the R code.
* RStudio uses (as default) TextMate (Text editor for MacOS)
highlighting for R code.
* The R package "highr" just defines CSS classes and

Access to R help database
Hi,
from the documentation of help.search I think that fields like "concept"
and "keywords" in the R help database exists. How can I access them from R?
If I do
> help<-help.search("blabla")
> colnames(help$matches)
[1] "topic" "title" "Package" "LibPath"
then I get back only back these 4 fields.

legend: interplay between title and y.intersp
Hi,
my MWE is not working as expected:
plot(c(0,1), c(0,1), type="n")
legend("top", legend=c("", "", "a"), col=c("blue", "red", "green"),
title="test", y.intersp=0.2, lwd=1)
The lines are not below the title. I want (nearby) lines as in the plot,
but below the title. Is there a way to achieve this?

Dynamically create a (convenience) function in a package
Hi,
n a package, I have a data object with attributes, and I want to
dynamically create a convenience function to access those attributes.
This way, instead of using attr(x, "number"), I would like to use number(x).
Because I don't know in advance which attributes the data object may
have, I've used the following algorithm:

R 2.1.1 installation fails under Suse 10.0 (PR#8533)
Full_Name: Sigbert Klinke
Version: 2.1.1
OS: Suse Linux 10.0 (Full DVD)
Submission from: (NULL) (141.20.100.252)
Suse 10.0 installs only a Fortran 95 compiler with g77 compability mode. Using
this leads in "configure" to an abortion with problems about "FPICFLAGS".
Deinstalling g77 compatiblity mode, using f2c, compiles R. But after calling R()
