incompatibilities between 0.90 and 0.99?
Maybe this is dumb, but I seem to be having problems reading a file saved in R
v. 0.99 into R 0.90.1 (in a different machine).
I did
>save(test1, file="test1.RData")
then I tried to read that data file in R 0.90.1:
>load("test1.RData")
Error in load("test1.RData") : restore file corrupted -- no data loaded
More info:
- both machines are running Linux;

Ordinal categorical data with GLM
Hello All:
I am trying to replicate the results of an example found in Alan
Agresti's "Categorical Data Analysis" on pages 267-269. The example is
one of a 2 x 2 cross-classification table of ordinal counts: job
satisfaction and income.
I am able to get Agresti's results for the independence model (G^2 =
12.03 with df = 9) assuming as he does that the data is nominal, but

accessing virtual memory
Hello R users,
I am doing some work with a large data set but am running out
of memory. I understand that R dynamically loads memory as
it needs it, but for some reason it cannot seem to find my virtual
memory. It's limit is about 256M (my hard memory) regardless
of the amount of virtual memory. I'm running R 1.30 on Windows
NT.
Am I missing an easy fix here?
Many thanks in advance,

chi square test is not appropriate? but what test is
Hallo all
Suppose I have a summary amount of various colours used in
different areas
colour plastic paint
black 15.5 173.8
brown 6.0 523.2
green 2.5 6.4
red 77.1 237.4
yellow 144.6 77.3
It seems that there are some preferable colours in these two areas
(yellow in plastic, brown an red in paint).
The problem seems to me similar to chi square test but it is
intended for testing counts or

Identifying and characterizing strings of NA in a vector
Dear R users,
I was wondering if someone could suggest a few lines of code for my problem.
I want to count the number and the length of strings of NA in a vector.
For example:
vec <- c(1, 2, 1, NA, NA, 1, 2, NA, NA, NA, 3, 4, NA, NA)
has 2 strings of NA's of length 2 and 1 string of NA' of length 3.
I can easily count the number of NA's per vector, but I am having a hard
time

programming in R
I have a probably basic problem concerning the R language.
I will write some small R programs but don't really know how to start. Do I have
to create my files in some editor like emacs or can I write my code in the R
prompt? How to compile the code?
I haven't found any good manual parts about this subject.

Thanks a lot for your help!

loop para repetir valores de un vector
Hola a todos!
Estoy intentando crear un vector (alt) a partir de la repetición de valores
provenientes de otro vector (altitud).
A cada valor de altitud lo quiero repetir 1247 veces, y de ahi continuar
con el siguiente valor de altitud.
Probé varias cosas, pero esto me pareció lo más coherente:
altitud=read.csv("C:/Users/IER/Dropbox/Pasantia

Two questions
Greetings,
I have two questions that I could not answer from the
documentation.
A - ecdf and confidence intervals : Is there a (simple) way to generate
confidence intervals (95%) for a ecdf?
B - cross-validation of rpart trees : a colleague is using S to
generate decision tree and mentioned to me the use of cross-validation. Is
this function enabled in R ? if so, how should one proceed to
