Re: [R] testing slope
Hi, in order to avoid the parameter of x:v3 to be estimated, you can re-formulate the model. You fitted y~1+x+v2+v3+x:v2+x:v3 with 6 df Now you would fit y~0+v1+v2+v3+x:v1+x:v2) with 5 df as x:v3 is not included in the model, i.e. the parameter x:v3 is constrained to be zero. best, vito A toy example is following: x-1:100 #explanatory continuous variable f-factor(rep(1:3,length=100)) #categorical variable f-model.matrix(~f-1) xx-f*x X-cbind(f,xx) #design matrix colnames(X)[4:6]-c(xf1,xf2,xf3) b-c(2,5,-3,-2,3,0) #parameters y-X%*%b+rnorm(100,0,1) #response m0-lm(y~0+X) #full model m1-lm(y~0+X[,-6]) #reduced model anova(m0,m1) #test for nonnull slope - Original Message - From: Ronaldo Reis Jr. [EMAIL PROTECTED] To: R-Help [EMAIL PROTECTED] Sent: Tuesday, February 04, 2003 8:50 PM Subject: [R] testing slope Hi all, I try to test a linear slope using offset.

Re: [R] big ps-files
Why does it matter? Surely the time taken to read the file or send it to the printer is not important, and the actual files compress well for storage (about a factor of 6 with bzip2 on the example I tried). Which version of S-PLUS, which has had two completely separate postscript drivers? The ATT S version was written in the 1980s when this did matter and is somewhat optimized for compact code. I've just done a quick comparison on the MASS4 ch05 script using Linux. S-PLUS 6.1 produces 212Kb, R 1.6.2 produces 596Kb. These compressed to 48 and 108Kb respectively.

The first time I used barplot() in R, I was shocked to see the colors.) As an example, one example in ?layout draws a scatterplot with histograms drawn on the margins.

Box 2000, RY84-16Rahway, NJ 07065 mailto:[EMAIL PROTECTED] Andy, This is an extrapolation beyond known data by me, but I would suspect that one plausible reason is that since barplot can do grouped bars and stacked bars, the original author decided to set a single default multiple color vector for all cases. This would be one approach rather than checking to see what type of barplot was being drawn and using a single color for the scenario you are using or a multiple color vector for grouped/stacked bars. It is obviously easy enough to add 'col = color' to the barplot() arguments to use a single color of your choosing or an alternate multiple color vector. To change the default behavior now would likely break other code in use. My two cents Regards, Marc Schwartz __ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help

You can easily get a single color, eg data(VADeaths) barplot(VADeaths, beside=TRUE, col=thistle) The colours themselves are definitely not ideal.

What I do - explained in the R man page - is
R example.R example.out
and I have found it useful (for some reason I can't recall) to
use the --vanilla option in these cases:
R --vanilla example.R example.out
It's useful because it won't work otherwise -- you need --save, --no-save
or --vanilla.
You can also send small amounts of R code into stdin directly. For
example, a shell script Sweave.sh to run Sweave can be written as
#!/bin/sh
R --vanilla SweaveSh.R /dev/null $1
with SweaveSh.R being
library(tools)
Sweave(commandArgs()[3])
or more elegantly in a single file as
#!/bin/sh
echo library(tools);Sweave('$1') | /usr/local/bin/R --vanilla --silent

This is covered in the rw-FAQ, and is a bug in some (obselete and unsupported by Microsoft) versions of Windows.

Re: [R] R as a `script'
In R 1.6.2 you can do this if you start the script with #! /path/to/r_home/lib/R/bin/R.bin provided that you first define the environment variables R_HOME and LD_LIBRARY_PATH as they are defined in the R shell script (/usr/bin/R in your case). I've only tested this running on Sun Solaris. I can't claim to have done extensive testing for pitfalls (i.e., pitfalls that aren't obvious to me!). -Don At 2:30 PM +0100 2/5/03, Havard Rue wrote: is there any way i can use R as a tool for scripts in unix, as wotan[hrue]$ cat example.R #!/usr/bin/R x=1 havard -- Havard Rue Department of Mathematical Sciences Norwegian University of Science and Technology N-7491 Trondheim, Norway Voice: +47-7359-3533URL : http://www.math.ntnu.no/~hrue Fax : +47-7359-3524Email: [EMAIL PROTECTED] __ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help -- -- Don MacQueen Environmental Protection Department Lawrence Livermore National Laboratory Livermore, CA, USA -- __ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] commandArgs() prints warnings to STDOUT - correction
I realized that it is not commandArgs() rather R itslef that prints the warning to the stdout (which is still not desirable of course): $ R --no-save --no-restore --silent A /dev/null 2 /dev/null ARGUMENT 'A' __ignored__ ===original message below Dear R-Users, I was glad to hear that there is an ongoing work to make R more easily runnable as a batch. I'd like to raise two issues in this regards: 1. commandArgs() prints warnings to STDOUT rather than to STDERR, see example below $ cat foo.R argv - commandArgs() $ R --no-save --no-restore --silent A foo.R 2 /dev/null ARGUMENT 'A' __ignored__ argv - commandArgs() 2. It should be possible to turn off echoing of R commands, the '' lines above. Please let me know if it is already there.

Thanks much for any input, The new `survey' package does this for means, tables, glm and cox models. It would be pretty easy to add support for the parametric survival models if there were any demand. It incorporates weights, stratification, clustering, and the finite population correction to variance if desired. -thomas __ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] .Rprofile, .Rfirst, and .Rdata
Hi all, After a short hiatus away from R I have found that it's changed a bit. I used to keep a definition of .First in .Rprofile that did a couple of things on startup (load a couple of libraries). Now, I've discovered that when I change the definition of .First in .Rprofile it doesn't change anything when I start up, because .First is held over in .Rdata from the last session. The manual states that now .Rdata is loaded last, as intended. My question is, how do I change what's in .First (or any other variable, for that matter), if .Rdata will always override my changes? (I'd prefer not to have to do it manually, and I'd prefer to have all the other data preserved, rather than just leaving out .Rdata) Dave R. __ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] Call C routine problem
When I call C function from Splus, I often meet this problem:
Problem: Couldn't find a function definition for Stest
My c function is saved as 'test.c' (the function is also named as 'test'
My splus function is saved as 'Stest', such as
Stest -
function(d,f)
{
.C(test,
as.integer(d),
as.single(f))
}
Assume my files (test.c and Stest) have been stored in the directory ''work''
I have done the following steps in this directory:
(1) Splus CHAPTER test.c
(2) Splus make
(3) Splus
(4) d-10
f-rep(0,d)
result-Stest(d,f)
then the error message is :
Problem: Couldn't find a function definition for Stest
What am I wrong???
Thank you for your help in advance!!!

[R] About STEM Plot in R
Hey Does anybody know if R can plot the 3-dimensinal stem graphs? In Matlab, there is such similare function to plot 3D plots, stem3(X,Y, Z), where X, Y , Z (column vectors) are coordinate values of data points. Thanks.
