Dear Forum,
I have a class variable 1 (populations A-E), and two other class variables,
variable 2 and variable 3. What I want is to see if the combination of var 2

I found several packages like ade4, with pcaiv function a
Thank you Terry, that answered all questions.
As a suggestion, help page for ridge() might indicate that the ridge
term simultaneously introduces predictors and penalizes them.

as usual with such specific questions, it is a good idea to have the

your message privately to the plm authors with the following comment:

Hi
Does anyone know if there is a function like survdiff which can also handle
left-truncated and right-censored data? When I use it on left-truncated and
right-censored data I get an error message saying Right censored data only.
Many thanks

Hi, R users,
Is there any package for penalized logistic regression with more than two
response classes? I read the manual for stepPlr, but it seems it's only for
binary case.
Thank you,

Hi, I have been using R for a bit, but never came across this simple

Hello R users,
I'm trying to understand the meaning of the results returned by the command

I thought it was the matrix with the fitted values for each term (value of

Yes, mean of a one element object is meanless, but I'm trying to avoid a
ifelse in the sentence.
The result of mean values of x and y is added at each loop to a data.frame
(or any other object that could speed up the loop.

Dear Paulo,
Your object is a named vector. Apply() and colMeans() only work on
matrices and dataframes. So you need to convert the vector to a matrix
or data.frame. See the example below. Please not that calculating the
mean of one element is a waiste of time.
