Error message in vars package
...an object of class "varest" generated by VAR() -exactly the class of object that var.2c is:

May it be that I'm using the latest version of R -in Windows- (ie 2.15.3 ), perhaps?

Pairwise deletion in a linear regression and in a GLM ?
Dear useRs,
In a thesis, I found a mention of the use of pairwise deletion in linear
regression and GLM (binomial family).
The author said that he has used R to do the statistics, but I did not find
the option allowing pairwise deletion in both lm and glm functions. Is
there somewhere a package allowing that ?
Thanks,
Arnaud

columns called X rename Y
I have a data. frame to which you want to change the names to some of their
columns.
For example:

[1:10], otros = 2:11)
List their names:
> names (Seba)

Calculating Cumulative Incidence Function
Hello,
I have a problem regarding calculation of Cumulative Incidence Function.
The event of interest is failure of bone-marrow transplantation, which may
occur due to relapse or death in remission. The data set that I have
consists of- lifetime variable, two indicator variables-one for relapse and
one for death in remission, and the other variables are donor type (having

to check if a character string is in a group of character strings
Hello,
How can I judge if a string is in a group of string? For example, I would like to have
if (subpool in pool){
}else{
}
Where
> pool = c("s1","s2")
> subpool = c("s1")
How can I write the "subpool in pool" right in R?
Thanks very much!
Cheers,

Need an advise for bayesian estimate
Hi R bayesians,
I need an advise how to resolve the two different estimates applying a
traditional glm (TG) and a bayes glm (BG), and different results depending
on the data formats of response data and the prior specs using bayesglm in
R. I'm not familiar with bayes estimate and my colleague asked me to look
into this because the EPA from France reported a quite different estimates

Code to fetch summary info from vector
Hi all,
Thanks in advance for any help.
I have a vector "b":
b=c(1,1,1,2,3,4,3,2,1,1,1,1,1,2,3,4,5,4,3.5,3,2,1,1,1)
Imagine b is river flow throughout time.
I would like some code that will generate the following information:
number of individual 'periods' where b>1 (= 2 in this case)
period 1 length = 5, max = 4
period 2 length = 8, max = 5

How to plot doubles series with different location using plotCI

I would
like to create two series of plotted mean values and error bars, yet with

Plotting of
first series using plotCI with the standard arguments goes without any problem.
However I do not succeed to add the second series in the same plot, which
should be horizontally shifted from the first series along the x-axis. The “add=TRUE”
