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'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: 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 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 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: 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: 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: 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: 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

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: 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: Are your undergraduate students receptive to learning R, as a rule? Most of the time, mine really like it. But this semester, they act as though they are being eaten by rats when learning R. They are not trying at all. Any similar experiences? If anyone has any good ideas, I would be THRILLED to hear them, as I am using R in Summer School. Thanks, Sincerely, Erin Hodgess

Dear R People: In S Plus, if you have a function which calls the plot function several times, you get several "pages" of graphics output. Is there an eqivalent in R, please?

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! Sincerely, Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences

Dear R People: Is there any way to take a Windows version of R, compiled from source, compress it, and put it on a Unix-like environment, please? thanks in advance, Sincerely, Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: hodgess at gator.uhd.edu

Dear R People: I'm trying to use the garchFit function from the library(fSeries) However, R freezes every time that I use it. Is anyone else having this problem, please? Thanks in advance!

Dear R People: I'm having trouble with selecting a mirror to download packages. When I select the location, R just sits. When I try to cancel the program, it never quits. Has anyone else run into this, please? It only happens on my laptop, not my desktop. My inclination is to say that it might be a problem with a firewall, but I thought I would check here as well.
