bash-like history mechanism and prompt settings
Hi,
I have a couple of questions:
* would it be possible to add more information on the history, for
example the number of the command and a timestamp. With the number of
command, one could do some stuff like in a terminal to recall a specific
command :
$ !45
and with the timestamp, one could imagine to ask for commands that were
typed in a given interval of time. For example :

hello World problem
Hi,
I'm trying to build a simple R package 'helloWorld' with just one
function that prints 'hello World' on the C side.
I agree that it is completely useless, but I just start mixing R and C.
My C file is as follows :
#include <stdio.h>
void helloWorld() {
printf("hello world !\n") ;
}
When I call it from R, here is what happens :

javascript device for R
Hi,
Has anyone started a javascript device for R.
I don't see something like that googling or at on
http://www.stat.auckland.ac.nz/~paul/R/devices.html
For example, using that graphics library :
http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm
(I cc that message to the author.)
ps : this is not a feature request, i will do it. But if someone has
started that, let me know.

pattern in history
Hi,
Sometimes I need to consult the history of commands that are matching a
regex, so I modified the utils::history function for that purpose. I
found it useful.
I append the code ( I only added the two lines with #**)
Romain.
history2 <-
function (pattern="", max.show = 25, reverse = FALSE, unique =
pattern!="", ...)
{
file1 <- tempfile("Rrawhist")

www.r-project.org
Dear R users and developpers,
My question is adressed to both of you, so I choose R-help to post it.
Are there any plans to jazz up the main R website : http://www.r-project.org
The look it have now is the same for a long time and kind of sad
compared to other statistical package's website. Of course, the
comparison is not fair, since companies are paying web designers to draw

superimpose density line over hist
Hi all,
I'm trying to superimpose a rchisq density line over a histogram with
something like:
hist(alnlength)
lines(density(rchisq(length(alnlength), 4)),col="red")
But the rchisq line won't appear anywhere,
Anyone knows what I am missing here?
Thanks in advance,
Albert.

the graph gallery strikes back
Hello useRs and helpRs,
Some time ago, in a gallaxy far away (here is the thread :
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46532.html ) we
discussed about a graph gallery showing the power of R in that domain. I
did some work around that, and there is a (pretty advanced) draft here :

For instance, there are some of my graphs,

lme4: Error in getResponseFormula(form) : "Form" must be a two sided formula
I'm sure I'm being stupid so flame away...
R2.2.1 on Windoze (boohoo) latest updates of packages.
I'm exploring a dataset (land) with three variables looking at an

the baseline score (SFQ.BASELINE) as covariate and the following work

difference between rnorm(1000, 0, 1) and running rnorm(500, 0, 1) twice
Hi R users
This looks a simple question
Is there any difference between between rnorm(1000,0,1) and running
rnorm(500,0,1) twice in terms of outcome ?

R Commenting Style
I seem to remember reading somewhere about some style
guide regarding R the number of comment characters (#)
prior to the comment meaning something.
Anyone know to what I'm referring? Where?

dendrogram branches with different lty
Dear r-list,
I am trying to visually seperate the two main clusters of a dendrogram.
The idea is to use:
'edgePar=list(lty=3)' for 'dend1[[1]]' and
'edgePar=list(lty=1)' for 'dend1[[2]]'
I have not found a way to solve this. Any suggestions?

About regression and plot
Dear R-help,
This is my first R day. I want to ask some more beginner's questions.
Q1. How can I obtain the covariance matrix for parameter estimates of a multiple regression? I checked ?lm but didn't get the information.
Q2. How can I see the old graphs in the graph window?
Q3. Can R plot animated graph? For example, I want to see the dynamic change of a 2D graph during a time

Commented version of the home page graphics code
Folks,
I was drawn to R, like many others, partly for the opportunity
to draw nice, colorful graphs (occasionally ones with meaning, too :-)
). I am still quite a newbie to R.
As such, I have been trying to understand the code for the graphics on
the home page (the ones from the 2004 contest -- the dendrogram, the
cluster plot with different coloured circles, etc.) I was wondering
whether anyone

R Graph Gallery : categorization of the graphs
Hello all,
It seems that the next improvement to the R Graph Gallery is
categorization of the graphics, that way each graph will be easier to
find. That step should be done *carefully* if we want to avoid the
opposite side-effect : graph not reachable through the categories.
That's why the wisdom of the R community is required.
Graphics will be classified in :
- categories

Plotting contour & filled.contour in one graph
Dear All,
I have a question on overlaying a filled.contour (e.g. on soil properties data) and contour (by elevation) in one graph. Both have the same z matrix dimension. I'm able to overlay both graph, but the plots dimension did not overlap well on the same plots. How can I have both filled.contour and contour on the same graph? The commands that I have written are as follows:

The R Graph Gallery {was boxplot statistics}
I agree with Martin "R Graph Gallery" has a lot of neat stuff.
I also think there should be a on CRAN website a list of "R websites". And
in a perfect world one of the search engines scope would get extended to
search them all.

creating empty cells with table()
Hello,
Suppose I simulate 20 observations from the Poisson distribution
with lambda = 4. I can summarize these values using table() and
then feed that to barplot() for a graph.
Problem: if there are empty categories (e.g. 0) or empty categories
within the range of the data (e.g. observations for 6, 7, 9), barplot()
does not include the empty cells in the x-axis of the plot. Is there
any way to
