Hello R helpers:

I would like to obtain probability of an event for one single patient as a
function of time (from survfit.coxph) object, as I want to find what is the
probability of an event say at 1 month and what is the probability of an
event at 80 months and compare. So I tried the following but it fails

summary.lme and anova question
Dear all,
When analyzing data from a climate change experiment using linear mixed-effects models, I recently
came across a situation where:
- the summary(model) showed a significant difference between the levels of a two-level factor,
- while the anova(model) showed no significance for that factor (see below).
My question now is: Is the anova.lme() approach correct for that model? And why does

ccf (cross correlation function) problems
Hello everybody,
I am sorry if my questions are too simple or not easily understandable. I’m
not a native English speaker and this is my first analysis using this
function.
I have a problem with a cross correlation function and I would like to
understand how I have to perform it in R.
I have yearly data of an independent variable (x) from 1982 to 2010, and I

Pairwise comparisons/contrasts from a coxph model?
Hello,
this is probably more a statistical question than an R-specific problem, but
I'll risk it.
I've fitted a Cox Proportional hazard model with one factor Treatment (seven
levels) as a predictor variable. The general Null hypothesis (all groups
show the same survival behaviour) is clearly rejected. Now, is there any
(statistically sensible) way of doing pairwise comparisons and/or

One way ANOVA with NO model
I'd like to do a simple one-way ANOVA comparing the means of 6
groups. But it seems like the only way to do an ANOVA in R is to
specify some sort of model, where there is an outcome or dependent
variable that is a function of independent variables (linear model).
But I don't have a linear model, I just want to do a simple ANOVA
(and f-test) to compare the means. How do I do

Summary statistics & plots of repeated measures data
I'm an R novice and my colleagues are about to convince me to get my
data into SPSS, which will presumably be easier for someone who
doesn't live in R to point and click his way into some kind of
analysis that might be meaningful.
I've got two groups of subjects (classkey in the table below).
They've each received several different treatments. One measure is a

ts model challenge (transfer function)
Dear useRs,
I am trying to model a time series with a transfer function. I think
it can be put into the ARMA framework, and estimated with the 'arima'
function (and others have made similar comments on this list). I have
tried to do that, but the results have so far been disappointing.
Maybe I am trying to make 'arima' do something it can't...
