Dear helpers, I am trying to use the mda package downloaded from the R website, but the data set has missing values so I got an error message. Should I manually handle these missing values? I was trying to read the documents to specify any option related to missing values, but I did not find it. Please forgive me if I ignore something obvious. Thanks, Zhu Wang Statistical Science Department

R people, I need to know if is possible to make data mining with R. If so, is there any manual or somewhere/one to consult about that. Thank you very much Adri?n

I've put all ``current'' add-on packages into CRAN's source/contrib tree and created an INDEX file (attached below).

In the near future, I am hoping for the following: oz (Bill

Anyone know if it is possible to get the R scripts used in the "The Elements of Statistical Learning" book? It is a great book but sometimes some help would be useful to replicate the results presented in the book and so, understood things better. Thanks Manuel -- View this message in context:

Hello All, Recently, I was asked to help out with an SEM cross-validation analysis. Initially, the project was based on "sample-splitting" where half of cases were randomly assigned to a training sample and half to a testing sample. Attempts to replicate a model developed in the training sample using the testing sample were not entirely successful. A number of parameter estimates were

This ancient bug was tracked to the acepack library, line 556 in line src/avas.f The troublesome line is: if (x(n).gt.x(1)) go to 30 Since the input arguments are empty, referencing x(1) and x(n) cause a Segmentation fault, and cause R to crash. Acepack author and maintainer Rob Tibshirani <tibs at utstat.toronto.edu> has been contacted with this information. This is not a

Hi All,  I have been trying to use glmnet package to do LASSO linear regression. my x data is a matrix n_row by n_col and y is a vector of size n_row corresponding to the vector data. The number of n_col is much more larger than the number of n_row. I do the following: fits = glmnet(x, y, family="multinomial")I have been following this

In an .Rd example for a package, I want to use data from another package, but avoid loading the entire package and avoid errors/warnings if that other package is not available. If I don't care about loading the other package, I can just do: if (require("ElemStatLearn", quietly=TRUE)) { data(prostate) # rest of example } I'd rather just be able to do something like:
