Does anyone know R is to be cited in a publication? I've looked everywhere
on the website and cannot find this.
Thanks,

Extracting values from linear models
Hello:
I want to use values from the output of linear models done using permuted
data to construct a random distribution. The problem I am having is the
extraction of a value, say the p-value or the regression coefficient, from
the summary of a linear model. When summarizing a linear model I get this:
Call:
lm(formula = fitness ~ mm)
Residuals:
Min 1Q Median 3Q Max

Importing module into R library
Hello,
I am basically familiar with R and am trying to import a module that someone
else has written. I know that it must go into the R library but even after
I place the file there R doesn't recognize it. The module is maanova,
available from the Churchill lab group for analysis of microarray data, if
anyone is familiar with it. Any ideas/help?
Thanks,
Heather

Using MAANOVA functions
Dear R-users:
I am using the package MAANOVA to analyze microarray data and have
encountered problems when trying to plot data. I have tried emailing a
MAANOVA discussion group, as well as the author of the package, and have not
yet received a response so I am hoping that someone on this listserv can be
of assistance.
There are several functions in MAANOVA (riplot, resiplot) which call the

init.data function error
We had been using R1.2.3 "print tip lowess function" as described by
Terry Speed's group to normalize microarray data and up until this week
the commands we were using were working fine.
First, we load our data using arrayname<-read.table("filename",
header=T)
and then check that the table is OK.
We format the data list using setup1<-init.data() and usually get a

standardized residuals (rstandard & plot.lm) (PR#8468)
This bug is not quite fixed - the example from my original report now =
works using R-2.2.1, but
plot(Uniform, 6)
does not. The bug is due to

polygon angle option perpendicular to axis
Thanks for the question. Here is a sample of the code for my plot:
Top = c(34, 39, 42, 45, 46, 41, 41, 40, 43, 38, 33, 33)
Bottom = c(24, 29, 32, 36, 32, 34, 32,41, 40, 39, 29, 24)

polygon angle option perpendicular to axis
The angle is not based on the polygon edges, but it can seem that way if you do not use the asp=1 argument in your plot. Try this example,

> x <- c(1, 3, 5, 3)
> y <- c(3, 5, 3, 1)
> polygon(x, y, angle=0, density=10)

Announce: edtdbg, integrating R's debug() with your text editor
I've just developed edtdbg, a small package that integrates R's debug()
with one's text editor.
Excerpt from the README file:
Goal
The debug() function in R is primitive. My goal was to make it more
usable by integrating it with one's text editor. Hence I wrote the
package here, edtdbg. Its features include:

Forcing zero intercept in two predictor case - stat question not R question
When one is doing simple regression and needs to force a zero intercept
( for whatever reason. I realize it's a controversial issue ),
then subtracting the means of the left hand side and the right hand side
from themselves does the trick. Does anyone know if there is a
similar trick when the RHS has two variables ? Thanks.

polygon angle option perpendicular to axis
Filling polygons with lines is a throwback to the time when the height
of quality graphics was the mechanical pen plotter (a device that used
a pen in a mechanical arm to draw the plot on a piece of paper).
Computing and printing technology has advanced quite a bit from that
day, so you may want to reconsider why you want polygons filled with
lines instead of just a solid color (and I consider

Question from Newbie on PostScript and Multiple Plots
Hi,
As I'm pretty new to R I hope this question isn't too basic.
I am currently looping through my dataset and for each iteration am
producing three separate plots. When I output these plots to the screen
they are nicely grouped as three plots per page, however, when I try to send
it to a PostScript file I get one page for each plot. I have adjusted my
postscript options so that my

Searching for antilog function
Dear R-users,
I have a basic question about how to determine the antilog of a variable.
Say I have some number, x, which is a factor of 2 such that x = 2^y. I
want to figure out what y is, i.e. I am looking for the antilog base 2 of x.
I have found log2 in the Reference Manual. But I am struggling how to
get the antilog of that.
Any help will be appreciated!

str and class
In previous versions of the gnm package, the terms component of "gnm"
objects had a "classID" attribute. This caused problems when used with
str as the following simple example illustrates:
> x <- 1
> attr(x, "classID") <- "type1"
> str(x)

Test of Parallel Regression Assumption in R

regression is appropriate. I cannot find a function to conduct such a test.

mapping groups of states without interior borders
I have been using the "map" function in R and I was wondering if there is a way to map multi-state regions just showing the outline of the region without interior state borders. For instance, I am calculating aggregated statistics using 10 multi-state regions. I would like to color-code individual states based on my dataset but then to create black outlines around each of these 10

Host Key verification issue
Hello,
I have script that I run remotely on a server, using ssh config with a 'command' call in the authorized keys file. I can successfully run this from one of my servers, but when I try from 2 other machines, I receive a Host Key Verification Failed error.
When I remove the 'command' from the call from authorized keys on the remote server, I can successfully connect to the
