Help with Python, R and RPY
Hi All:
Walter Moreira wrote a small extension module for using the R programming
language from within Python. Tim Church's example at
http://www.cmat.edu.uy/~walterm/rpy was so compelling, I could not resist
installing it on my Linux Mandrake 8.1 box.
But I ran into problems.
I have installed on Mandrake 8.1 both python and R:

Point labels
Hello,
Is there an option I can easily set to put labels next to the points in a
simple plot?
The closest I got to it was to use the option pch, but this replaces the
point symbol with the character specified, and it is not what I want.
Thanks

Problem with ties in rank()
Hello All:
I have a vector of data, z
> z
[1] 0.1 0.1 0.1 0.1 0.2 0.2 0.3 0.3 0.3 0.4 0.5 0.5 0.5 0.7
0.7 0.7 0.9 0.9 1.1
[20] 1.1 1.2 1.3 1.4
The first 4 elements have values of 0.1 followed 2 elements with values 0.2.
When I invoke rank(z), I expected to get (1+2+3+4)/4 = 2.5 for the first 4
elements in the ranking and (5+6)/2 = 5.5 for elements 5 and 6. But what I

R Libraries for ORDINAL categorical data
Hello All:
I know the function loglin() and loglm() from librarary(MASS) performs
analysis on nominal categorical data. Are there any libraries, functions or
examples available for analysis of ordinal categorical data? I have in mind
procedures that can replicate results in Alan Agresti (1984) "Analysis of
Ordinal Categorical Data."

More on ties with rank()
I am grateful to Prof. Ripley for his explanation. Indeed, rounding explains
it all.
I take the difference between two vectors and call it "z"

ordering x's and y's
Hello ALL:
How do I get R to list all possible orderings of 2 x's and 3 y's? It should
look like this (which rows appear first is unimportant):
x x y y y
x y x y y
x y y x y
x y y y x
y x x y y
y x y x y
y x y y x
y y x x y
y y x y x

Have any of you succeeded in getting hold of Peter Daglaard's book,

Sampling from a population
Hi ALL:
Suppose you have a population of N <- 5 observations, x <- c(43, 28, 7, 61, 39). From that you can draw a maximum of 10 samples without replacement of size n <- 3. (Command choose(N,n) yields 10). For instance the samples I seek are
43, 61, 7
39, 7, 28 ...etc
How can I get R to do that for me, to get an exhaustive list of samples of size n drawn without replacement

Resampling Stats software
Hi,
I am new to R (I have most of my experience in SAS and SPSS). I was
wondering if anyone has used both Resampling Stats and R, and could comment
on strengths/relationships. Also, I have no clue on how to do the various
examples from the book "Resampling: The New Statistics" in R. Can anyone
give me some possible starting points? Or websites/books?
Thanks,
Brandon
