Hello:
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
Dear Derek, dear list,
A couple suggestions (and more) :
0) check that your problem can't be expressed in terms of what glmer()
(lme4(a|b)? package(s)) can solve. I use this often, and am quite
impressed with its abilities.
1) Why not modeling that directly in BUGS ? That might not be easy,
I have a set of results where I have the eyesight power of both left and right
eyes for each participant (e.g. 0.75, 0.5). Each participant then had to throw
basketballs into a hoop and the number of successful throws was recorded.
I would like to do two things:
1. Test whether the eyesight
Hi Mike, Hi Uwe,
thanks for your reply.
The main thing is that we have mixed OSs. On the one hand we have Linux,
on the other WinXP. I need the same version of packages and R on both
systems. Otherwise I cant explain my colleagues why error messages are
reproduceable on only one system.
Thank you guys I learnt a lot .
But when I tried to run the library(ecodist) function, R says there is no
package called ecodist.
why?

Hi Jonathan,thanks a lot! Mine is windows operating system so I will
try other ways .
About your question, do you want to get a matrix like this:
0 1 2 3 ...1817393 5524385
0687
0 64
0 71
0 55
...
Try this:
l - sapply(c(4, 3, 2), q.1)
aggregate(V3 ~ V1 + V2, as.data.frame(do.call(rbind, l)), mean)

Hi all,
Version 0.2.2 of the googVis package has been released on CRAN and
will be available from your local CRAN mirror in due course.
googleVis provides an interface between R and the Google Visualisation
API. The functions of the package allow users to visualise data
stored in R with the
By any chance is there an R package that may contain functionality similar to
the frestimate in Matlab/Simulink.
Here is the URL for a description of the frestimate functionality:

Thank you again for any feedback.
Dear R world,
Do you know about a function that would capitalize in the correct manner
first and family names?
I found in the cwhmisc only the CapLeading function, but it just does not do
the job, taking care only to capitalize the first letter of a word.
I am looking for a function that would
Have you done a google search, looked on CRAN, searched the archives,
or looked at the task views? I can't be of any help, but maybe one of
those places could be.
HTH,
Stephen

Hello Samaire,
I don't know much about eyesight measurements (other than that my own
would probably be 0.1, 0.2) but I'll attempt some suggestions...
For objective (1) you will have to define what you mean by
significantly different. If you had data on left/right values from a
larger population
