X11 error in png
Hi all,
When I ran a script containing the following codes:

including Sweave tangled code in '.Rnw' document
Hello List,
I have been using Sweave for my homework this last quarter and have been
very impressed at how much time and effort it saves me. I, however, have
run up against a problem which I have not been able to solve using any of
the Sweave/LaTeX tricks I know. I work through my homework one problem at a
time, typesetting equations and writing R code, etc. and occasionally use

Sensitivity and Specificity Forest Plots
Dear R Users,
Do you know of an existing function that allows the production of
sensitivity and specificity forest plots?
See the following for an example:

Sweave
I'm trying to (re)learn Sweave and run into some problems. I use now ubuntu
(8.10), emacs + ess.
Slowly getting upto speed on ess. I have a complete (hopefully) .Rnw file,
but the resulting .tex
will not compile. The file does not contain anything exotic, but it produces
pdf figures, and that
is where the problems come:

print and execute functions in a package namespace
Let's say I have a package that consists of a set of functions, fig1(),
fig2(), fig3() ..., each of which
produces a plot, and perhaps some printed output, e.g.,
fig1 <- function() plot(1:10)
fig2 <- function() plot(10:1)
fig3 <- function() {y<-sample(1:10,10); plot(y); y}
I'd like to produce a document (PDF or HTML) containing the listing of
each function and its output,

Five functions proposed for base
Dear r-devel,
Among the R functions I have written and later shared with colleagues,
there are five that I hope will become a part of the R base package. The
tasks are neither specific nor marginal, so rather than creating one more
'misc' package, I would be happy if the R Development Core Team would
adopt these functions and hammer them into shape.
The functions are available from

Identifying case by groups in a data frame
Hi everyone,
I would like to identify the case by groups that is just bigger that
avg plus sd. For example, using species as group and petal.wid as my
variable in the iris data.
What's the better way to doit? creating a function?
So,the question is to identify the single element of each species that is just larger than a cut-off point (i.e. larger than mean + sd)
I made this, but I can not

Rpart decision tree
Dear useRs:
I try to plot an rpart object but cannot get a nice tree structure plot. I
am using plot.rpart and text.rpart (please see below) but the branches that
connect the nodes overlap the text in the ellipses and rectangles. Is there
a way to get a clean nice tree plot (as in the Rpart Mayo report)? I work
under Windows and use R2.11.1 with rpart version 3.1-46.
Thank you.

error : unused argument(s) when boxplot
Dear all,
I am a total beginner in R, so sorry if this is the wrong place. I am using R 2.10.1 on a Mac (Mac OS 10.6.2).
I have this small dataset :

I have no problem reading the table, or getting the summary, but if I try boxplot(growth~sugar, ylab="growth", xlab="sugar", data=Dataset), I have the following error :

errorbar il lattice plot
Hi Everyone,
I would like to add errorbars to a lattice plot. I already have a function that
adds error bars to a plot (originally written by George Gilchrist) which takes
as arguments the coordinates of the point and then the size of the error bar. I
would like to integrate it in my lattice code but I seem to be stumped.
I can put the error bar function inside my code as if it were a panel

Automatic creation of file names
Dear R-Help members,
I have a question about how to save to the hard drive the one thousand
datasets I generated in a simulation. The datasets are created in a
"for" loop that repeatedly creates normally distributed datasets, such
as the example below:
Library(MASS)
for (number in 1:1000) {
dataset = mvrnorm(n = 400, mu = c(0,0,0),

too-large notches in boxplot (PR #7690)
PR #7690 points out that if the confidence intervals (+/-1.58
IQR/sqrt(n)) in a boxplot with notch=TRUE are larger than the
hinges -- which is most likely to happen for small n and asymmetric
distributions -- the resulting plot is ugly, e.g.:
set.seed(1001)
npts <- 5
X <- rnorm(2*npts,rep(3:4,each=npts),sd=1)
f <- factor(rep(1:2,each=npts))
boxplot(X~f)
boxplot(X~f,notch=TRUE)

add leading 0s to %d from png() {was Automatic creation of file names}
Dear useRs,
Is there a way to 'properly' format %d when plotting more than one
page on png()? 'Properly' means to me with leading 0s, so that the
PNGs become easy to navigate in a file/image browser. Lacking a better
solution I ended up using the code below, but would much prefer
something like
png("test_%d.png",bg="white",width=1000,height=700)

ANOVA stuffs_How to save each result from FOR command?
Dear R experts,
I'm new in R and a beginner in terms of statistics.
It should be simple question, but definitely difficult to solve it by
myself.
I'd like to see main effect of group(gender: sample size is
different(M:F=23:18) and one of condition(cond) and the interaction at each
subset from 90 datasets
So I perform anova 90 times using a command like below;

boxplots
Was there ever a convenient method provided to add boxplots to the current
plot at specified x values? There was a question by Martin Maechler some
time ago here, but I could seem to find any satisfactory resolution of it.
I see that there is an add=T option to boxplot and bxp, but I don't see
how to set the x-values.

Writing a list to a file !
Hi All,
This may be trivial in R but I have been trying with
out any success. I have a list of 100 elements each
having a sub list of different length. I would like to
write the list to a ASCII file. I tried with
write.table(), after converting my list to a matrix.
Now it looks like

self-split plot on multiple device
Hello!
I would plot more than 10 (this number is always different)
graphics on a figure with layout like 'mfrow=c(4,2)'.
There is some existing function able to open the right number of
device if number of graphics is done or I have to build it myself
with some 'IF.....ELSE.....'?
Thanks.

text-plotting math & regular mixed ?
Maybe embarassing, but I can't quickly find out how to do this:
Mix expression() text and regular text __in a variable__ for plotting:
I can easily do
plot(1,type="n",main=expression(paste("Plot of ", x ^ alpha, "; ", alpha==2.3)
However, if alpha is really just in a variable, I don't know what to do
alpha <- 2.3
ch.a <- format(alpha)
