Accessing the elements of a list
Hi R,
I wanted to know how do we access the elements of a list. In particular,
v=list(c(1,2,3,4,5),c(1,2,33,4,5),c(1,2,333,4,5),c(1,2,3333,4,5))
I want to access all the thirds items of the elements of the list. i.e.,
I want to access the elements, 3,33,333,3333. This can be done through
sapply as:
sapply(v,function(x) x[3])
But I need to access this without using

Question On CrossTable function in gmodels package
Hi R-users,
I have the following problem with CrossTable function within ?gmodels? package: the output of the function (format ?spss? and asresid=T) can not be stored within another object.
For example:
>library(gmodels)
>data(infert, package = "datasets")
> CrossTable(infert$education, infert$induced)->aa # the function prints everything ok on the screen
> aa # works

Error in Design package: dataset not found for options(datadist)
Hi,
Design isn't strictly an R base package, but maybe someone can explain
the following.
When lrm is called within a function, it can't find the dataset dd:

> age <- rnorm(30, 50, 10)
> cholesterol <- rnorm(30, 200, 25)

ROCR package not installing
I have tried installing the package (ROCR) with this command:
Install.packages(ROCR)
And with this command on the command line
R CMD INSTALL ROCR_1.0-4.tar.gz
But both times I get exactly the same error shown below, I don't understand
what is wrong, is this an error in the package code?
Thank you

Help with 'annotation' in GOHyperGParamsClass
Dear cateGOry experts,
hyperGTest documentation states that YEAST cannot be used as 'annotation'
when evaluating gene ontology representation status for a given set of

Because I am using a custom print I believe I need to create my own data

Hello all,
I would like to perform SVM-RFE (Guyon et al. 2002) in R and have only found
one implementation of this algorithm. The function belongs
to the MCRestimate package but when I try to use it I encounter a problem
- the function appears to be missing a required package or other function
that I simply cannot find available anywhere.

confused about CORREP cor.LRtest
After some struggling with the data format, non-standard in
BioConductor, I have gotten cor.balance in package CORREP to work. My
desire was to obtain maximum-likelihood p-values from the same data
object using cor.LRtest, but it appears that this function wants
something different, which I can't figure out from the documentation.
Briefly, my dataset consists of 36 samples from 12

val.prob in the Design package - Calibrated Brier Score
Hello,
I am using the val.prob function in the Design package. I understand how
the Brier quadratic error score is calculated, but I do not know how the
Brier score computed on the calibrated rather than raw predicted
probabilities (B cal) is calculated. My question is: how are the calibrated
probabilities calculated? Any explanation of this, or references to
explanations of this, would be
