Dear R People: I am trying to build a package (yet again!) I have both PCTex and WinEdt. I want the *.tex files to use WinEdt. How should I set that, please? Just in the path? Also, where would I get Rd.sty, please? Thanks, R Version 2.2.1 Windows Sincerely, Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: hodgess at

Dear R People: I have used the "latex" function from the Hmisc package and it is just great! However, I have a new question regarding that function: is there an option for summary(lm(y~x)), please? There are options for different types of objects, but I didn't see one for that. Maybe I just missed it. Thanks in advance! R for Windows Version 2.3.1 Sincerely, Erin Hodgess

Dear R People: When the D function is used for a symbolic derivative, an expression is returned, which is fine. How do you change that expression to a function, please? I've been experimenting with substitute and deparse, but no success yet. This is R 1.8.0 for Windows. thanks in advance for the help! Sincerely, Erin Hodgess mailto: hodgess at gator.uhd.edu

Hi Ryszard! There is a dist function in R. It's in the mva package. You can set the kind of distance that you want. Thanks, Erin mailto:hodgess at gator.uhd.edu

Dear R People: In the function "decompose", the object has the class of "decomposed.ts". (from package stats) I would like to see the class definition and the method for the plotting. However, when I use isClass("decomposed.ts") I get "FALSE". When I check getMethods("plot") there is no method for plot on decomposed.ts Any suggestions,

Dear R People: I am trying to split a character vector into a set of individual letters: Ideal: x3 <- c("dog") "d" "o" "g" I tried the following: > strsplit(x3) Error in strsplit(x3) : argument "split" is missing, with no default > strsplit(x3,1) [[1]] [1] "dog" I know that this is incredibly simple, but what am I doing

Dear R People: Could someone direct me to some documentation on the difference between S3 and S4 classes, please? For example, why would a person use one as opposed to another? Maybe pros and cons of each? Thanks in advance! R Version 2.2.0 (I'm downloading the new one this afternoon!) Windows. Happy New Year!

Dear R People: When will version 1.9 (for Windows) be ready, please? My reason for asking: there is an interesting library from Bioconductor called tkWidgets. However, it will only work with version 1.9.0 or higher. Are there ways around this, or should I just be patient? Thanks so much in advance!

Dear R People: Here is yet another strange problem. I'm using R in one of my classes. However, the computer lab has something called "Deep Freeze" and the students cannot save anything to the hard drive. I had R installed and things were working well. They would save their .Rdata files to disks. Now, we need to add more packages. We can't download and we can't bring

Dear R People: I'm using R in a time series class. This class is being broadcast live to 2 remote sites via closed circuit TV. My people at the remote sites are having a terrible time seeing the computer screen as it is broadcast(resolution issues). I have decided to put together Power Point slides for the teaching. I am currently saving the R screen as WMF files and inserting them into

Dear R People: Suppose I have the following; xa <- c("There are 5 dogs") I would like to have a new character vector such that xb[1] is There xb[2] is are xb[3] is 5 xb[4] is dogs Since the original vector has length 1, substring will not work. Any suggestions would be MOST welcome! thanks Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences

Dear R People: I downloaded the RPM for Red Hat Linux. How do I install this, please? When I looked at the R Intallation manual, it seemed to be referring to installing from source.

Dear R People: I was wondering if there were any packages for parallel programming in R. According to the R-help, at one time there was a package called SNOW. It doesn't seem to exist anymore. Any help would be much appreciated! Sincerely, Erin Hodgess mailto: hodgess@gator.uhd.edu [[alternative(swapped) HTML version deleted]]

Dear R People: Suppose I have the 4 numbers: 1,2,3,4. I would like to create a listing of the permutations of 4 items taken 4 at a time. Is there a built in function for that, please?

Dear R People: I will be teaching an undergraduate Design of Experiments class in the Spring Semester. It will be very much an applied course. My question, please: has anyone used R for a course like this, please? I've tried Rcmdr for a regression course and just plain command line for a time series course. Should I use Rcmdr, or teach them to use the command line, OR is there something

Dear R Users: Was there an answer to the question about using dev.print and win.print to print as horizontal = FALSE, please? I was working on it and I didn't find the solution. R 1.9.1 Windows Thanks, Erin Hodgess mailto: hodgess at gator.uhd.edu

Dear R people: I have a vector which runs from -1 to 1, by .1, inclusively. Easy to set up. x <- seq(-1,1,.1) I then sample 3 numbers from x. y <- sample(x, 3) Suppose one of my values is -0.7. I want to set up an interval around that y1 <- pmax(y-0.1,-1) y2 <- pmin(y+0.1,1) For the value -.7, the interval will run from -.8 to -.6. There will be several intervals. Again, nothing

Dear R People: I'm still struggling with sending methods and classes as part of creating a new package. Where does the .onLoad function go? Within R itself or in a file in one of the new package directories? Here are my latest efforts: Here's the last part of the woof1-Ex.Rout > library('woof1') Error in loadNamespace(package, c(which.lib.loc, lib.loc), keep.source =

Dear R People: On the Edit menu, there is a GUI preference tab. On the Font option, the highest value is 18. Has anyone ever had the font size set larger than that will any success, please?

Dear R People: Please excuse the off topic question, but I know that I'll get a good answer here. If a single author is writing a journal article, should she use "We performed a test" or "I performed a test", please? I had learned to use "we" without regard to the number of authors. Is that true, please? Thanks for the off topic help. Sincerely, Erin
