My First Function: cryptic error message
Dear List,
My first R function is a rip-off bagging algorithm from pg. 138 of
Everitt and Hothorn's "Handbook of Statistical Analyses using R"
(HSAUR). I'm using recursive partitioning to develop a set of useful
variables in diagnosing ADHD.
I'm running this in ESS in XEmacs 21.4.19, R 2.4.1 on Slackware Linux
11.0 with a 2.6 kernel.
This is almost an entire script,

Fwd: Re: [friday topic]: what exactly is statistical computing
This is a very fascinating discussion topic. I find I run into
some fundamental differences in interpretation of the phrase "statistical
computing". I think of it as writing programs or functions, such as R or packages
in R, and of understanding the numerical analysis behind these functions.
I exclude USING computer programs, such as R, for data analysis from my

[OT] emacs / xemacs for unix without compile
Dear All,
Is there a emacs/xemacs for unix without compiling it? If it is
possible, I prefer something that I can use immediately after putting
it on the unix server.
Is it possible or am I too stupid to ask this kind of question?
Thanks for your insight!

I am sorry for this off-topic post but think I can get great answer
from this list.
My question is what is the best OS on PC (laptop) for statistical

ERROR: 'latex' needed but missing on your system.
After successfully building R on Slackware Linux v11.0 I went to make
the documentation; the texi files went fine and then I hopefully issued
make dvi
after having gotten the warning to the effect of "You cannot build the
DVI or PDF manuals" during compilation. And, as expected I got the

Power for Linear Wald Test
Dear R-Helpers,
I'm searching for an R package that will produce power analyses for
linear Wald tests. I have conducted a thorough analysis and come up
with a pile of negative results (I'm the King, baby). I found
asypow, which applies to likelihood ratio tests. However, we
generally have the power to do Wald tests, I just need to prove it so
that we can publish it ;)

Reasons to Use R
Dear All,
The institute I work for is organizing an internal workshop for High
Performance Computing (HPC).
I am planning to attend it and talk a bit about fluid dynamics, but
there is also quite a lot of interest devoted to data post-processing
and management of huge data sets.
A lot of people are interested in image processing/pattern recognition
and statistic applied to geography/ecology, but I

off-topic question: Latex and R in industries
Latex and R are really cool stuff. I am just wondering how they are
used in industry. But based on my own experience, very rare. Why?
How about the opinion of other listers? Thanks.

an off-topic question -> model validation
Currently, I am working on a data mining project and plan to divide
the data table into 2 parts, one for modeling and the other for
validation to compare several models.
But I am not sure about the percentage of data I should use to build
the model and the one I should keep to validate the model.
Is there any literature reference about this topic?
Thank you so much!

Adjusting Yaxis (ylim) limits on a plotMeans(DV, IV1, IV2, error.bars="se")
Hello everyone,
I have tried to look for this everywhere and so far have no luck. I have a
plotMeans(DV, IV1, IV2, error.bars="se") graph that plots my data
(DV-continuous, IVs are factors, IV1 - two levels, IV2-four levels). I am
trying to increase a scale of my y-axis (to be consistent with my other
graphs), but unfortunately nothing works with "plotMeans" function, which

Oplocks question
What have people found with oplocks in the realm of really saving
time? Is it something that's always good to have in an environment
where two files being accessed simultaneously is rare? My shared
volume is an NFS on a remote server. Just curious what folks have
experienced.

About the statistics for ratio comparison
Hi
I have a table with four columns and 3 rows. I calculated the average for
each columns as average (A), average (B), average (C) and average (D), then
calculate the relative ratio as average (A)/average (B), and average
(C)/average (D). I would like to know how can I calculate the significance
between the two ratios.
Thanks,

Installing a package yet it will not work.
I want R to read my Microsoft Access database or maybe even a Sybase

following command:

Problem with CentOS 5.11 virtual machine
Hello --
We completed an installation of CentOS 5.11 32-bit onto a Vmware ESXi 6.0.0 appliance for the purpose of running a legacy application. The hardware in question is a Dell PowerEdge R730xd system. The Vmware tools utility was installed onto the virtual machine, and that initially provided access to the network. Once that was done, patches from the CentOS repository were installed onto the

If I have a list of number, say x<-c(0.1, 0.5, 0.6...), how to use a for()

OT: any recommendation for scripting language
Right now, I am using SAS and S+/R. As a new year resolution, I am
planning to learn a scripting language.
from statisticians' point of view, which scripting language is worth
to learn, perl, python, or any other recommendation? (Most likely, I
will be learning it in windows.) Since I am not in research, I will
prefer one widely used in industry and related to statistical work.

how to rescale the limits of yaxis rather than using the data range by default?
Dear Lister,
plot() is using the data range as the default limits of yaxis. Is
there any way I can change the limits? I just look at the help of
plot() and par() and couldn't find answers.
Thanks.
