Unbalanced parentheses printed by warnings() crash text editor
Hello everyone,
Hope it is the good place for this (I discuss the question of the right
place below).
Most of the time, warnings are more than 1000 characters long and thus are
truncated.
Most of the time, this generates printouts with unbalanced parentheses.
Intelligent text editors which do parentheses highlighting get very
confused with this.
After too many warnings, they give errors, and

smooth non cumulative baseline hazard in Cox model
Hi everyone.
There's been several threads on baseline hazard in Cox model but I think
they were all on cumulative baseline hazard,
for instance

"basehaz" in package survival seems to do a cumulative hazard.

covariate selection in cox model (counting process)
Hello everyone,
I am searching for a covariate selection procedure in a cox model formulated
as a counting process.
I use intervals, my formula looks like coxph(Surv(start,stop,status)~
x1+x2+...+cluster(id),robust=T) where id is a country code (I study
occurence of civil wars from 1962 to 1997).
I'd like something not based on p-values, since they have several flaws for
this purpose.

How to use the whole dataset (including between events) in Cox model (time-varying covariates) ?
Hello,
coxph does not use any information that are in the dataset between event
times (or "death times") , since computation only occurs at event times.
For instance, removing observations when there is no event at that time in
the whole dataset does not change the results:
> set.seed(1)
> data <-
as.data.frame(cbind(start=c(1:5,1:5,1:4),stop=c(2:6,2:6,2:5),status=c(rep(

constrained splines in GLM
Hi,
I would like to use constrained splines in a GLM model (Poisson link)
to take into account the nonlinear effect of some covariate. The
constraints I need are described below.
I have several variables that I need concurrently in the same model.
I looked at package mgcv but I do not know if/how I can use it in GLM (not
GAM) : I could
not manage to adapt the mono.con(mgcv) example to GLM.

Reading and treating multiple files....
Dear R helpers,
this is a question connex to the subject of reading large data-sets
- I have a large db (MySQL) ~80'000 records for each year / 120 variates
from which I extract relevant info to be treated in R (no problem)
Now each record in my db represents an experimental unit; moreover I will get - in a few days- a set of separate files(one for each records....~80'000 files pro

portable R editor
Hi,
I have been dreaming about a complete R environment on my USB stick for a long time. Now I finally want to realize it but what I am missing is a good, portable editor for R which has tabs and syntax highlighting, can execute code, has bookmarks and a little project file management facility pretty much like Tinn-R has those. I like Tinn-R but it seems like there is only a very old version of

BIC vz SBIC vz SIC
DeaRs,
I have a doubt about:
BIC (Bayesian Information Criterion)
SBIC (Schwartz Bayesian Informarion Criterion)
SIC (Schwartz Information Criterion)
In many references these are know as the same (eg. stepAIC() function) but I
just found a SAS8.2 output that show either the BIC and SIC values for a
logistic regression.. simillary values but different.
1) question: What are the differences?

Dear Duncan,
thank you very much, that is it! Indeed, there was activated in my
internet router the "telekom navigation help". When I am (or the system
is) looking for an not existent url, this "help" opens its own website.
After deactivation of telekom navigation help, the normal message
(server not found) comes. I never gave attention to this "help",

Fwd: Learning advanced R
I've found two problems in interpreting adv-r-master/book/build-book.r:
1. All pathes in build-book.r refer to the starting-directory "adv-r-master". However, the script build-book.r is located in the directory "book", which is located in directory "adv-r-master". Therefore, pathes starting at "." are wrong (should start at "..").

I'm faced with a problem applying the sp package: The projection argument in

maps for Russian Federation

I am interested in plotting maps visualizing spatial statistics in an
