slow start-up
Dear all,
I'm working with R 1.2.2 on win98 (256Mb RAM) with ESS 5.1.18.
It happens that the start-up is very slow. I don't know exactly how to measure, but with a simple watch I recorded 15 seconds, while the startup of S+ 2000 (Sqpe+4 under ESS) takes around 3 seconds.
Tha fact is that sometimes it takes almost a minute (58.30 sec recorded) for the prompt to appear! And ESS gives me an

Odds Ratio from Logistic Model
Hi all.
A simple question.
Is there a function to compute the Odds Ratio and its confidence intervall, from a logistic model (glm(.......,family=binomial....). I've written my own, but certainly someone did a better job.
Thank you in advance,
Stefano

library to R" ...
Thanks,

Cox model with interaction
Dear R users,
I am trying to fit a Cox model such as:
Surv(time,event) ~ X1+X1:X2
or

Hi all.
I'm trying to install the packages Rstreams and RPgSQL, but with no

I'm trying to install R on Mandriva 2006 distribution via rpm file with the

AW: Query: IRR Confidence Intervals
Hi Cristian,
I don't know about a R routine for exact CIs, but I found a function called
"ageadjust" using a gamma distribution approximation some time ago -take a
look at http://medepi.org/epitools/rfunctions/index.html.
That Webpage seems a bit outdated now, but the calculations given in the
ageadjust functions should still work, I think.
Maybe this helps;
regards
Heinrich.

I'm using the package "Genetics", and I'm interested in the computation of D'

by the LD() function. In the package documentation it is generally referred as

Histogram
Dear all,
I have a surprising problem with the representation of frequencies in a
histogram.
Consider, for example, the R code:
b<-rnorm(2000,3.5,0.3)
hist(b,freq=F)
When I plotted the histogram, I expected that values in the y-axis (the
probability) varied between 0 and 1. Instead, they varied within the
range 0-1.3.
Have you got any suggestion for obtaining a correct graph with
