Dear all, I am trying to my dataframe for the PLS analysis using the PLS package. However I have some trouble generating the correct dataframe. The main problem is how to use one name to represent several columns in the dataframe. The example dataframe in PLS package is called "sensory". I cannot directly read the data file since it's a binary file. If I use

Dear all, I am trying to calculate the fitted values using a ridge model (lm.ridge(), MASS library). Since the predict() does not work for lm.ridge object, I want to get the fitted_value from the coefficients information. The following are the codes I use: fit = lm.ridge(myY~myX,lambda=lamb,scales=F,coef=T) coeff = fit$coef However, it seems that "coeff" (or "fit$coef") is

Dear all, I have a question about how to get a matrix by combining a large number of columns from a data file. Suppose I read a file which have 1000 columns by: test = read.table("dat.txt", header=F) I know I could use "cbind()". It's easy to do when the number of columns is small (i.e. cbind(test$V1, test$V2)). But how about build a matrix "X" by combine the

Dear all, I am using different multiple regression models (OLS and principal component regression (PCR)) to make prediction of my test set. And those models come from the same training set, except that the number of variables or descriptors (columns of X) used in OLS is less than those used in PCR. And I use square correlation coefficient (r^2) and root mean square to see the relationship

Hello all I''ve been reading the security details at http://reductivelabs.com/trac/puppet/wiki/FileServingConfiguration#Security Can I confirm that even with "allow *", it will still only be clients who have had their certs signed by the puppet server who will be allowed access? Either way, it might be a good idea to clarify this in the documents. Many thanks Ian J Cottee

Hi, I think this has been discussed previously on the list, so apologies if I''m covering old ground but I''ve been using puppet to manage a few Rails applications which have dependencies on quite a few gems, so it''s getting to be a bit of an onerous task to manage them. It looks like the command line interface to gems doesn''t really support automated

Hi all, Today I came across something that I consider a bug. Would like to hear your opinions. Facts: - Using 0.22.1 from Debian Unstable on a Debian Testing machine - Recipes work on other machines The recipe in question is: # Keep home-dirs in sync file { "/home/tim": recurse => true, source =>
