dist(x,y)
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,

Expressions and Functions
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,

off topic publication question
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

off topic A4 paper
Dear R People:
Please excuse the off topic question.
What are the dimensions of A-4 Paper, please?
Actually, the question should read, "how do I set up a LaTex file
to fix A-4 paper, please?"
Thanks much!

decomposed.ts class and method
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,

Substring and strsplit
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

S3 vs. S4
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!

splitting a character vector
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

availability of version 1.9.0?
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:
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.

R and Power Point
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

Parallel processes
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!

exporting methods/classes
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:

DOE teaching suggestions?
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

intervals and data frames
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
