I am using R version 2.6.0 on Linux (CentOS 4.5) and have a problem with executing nearZeroVar function in the package caret. I am using the latest release of caret v4.17. I have a matrix X with 266 rows and 4 columns and when implementing nearZeroVar function from caret package I get following error message. > C <- nearZeroVar(X); Error in table(data, useNA = "no") : al...

On a Unix machine I ran caret::rfe using the multicore package, and I saved the resulting object using save(lm2, file = "lm2.RData"). [Reproducible example below.] When I try to load("lm2.RData") on my Windows laptop, I get Error in loadNamespace(name) : there is no package called 'multicore' I completely understand the error and I would like to ignore it and

Both functions can be run in parallel. - a set of functions (class "classDist") to computes the class centroids and covariance matrix for a training set for determining Mahalanobis distances of new samples to each class centroid - a faster version of nearZeroVar() due to Allan Engelhardt - two new data sets were added - several classes for examining the resampling results were added for estimating pair-wise differences in models and lattice visualizations The NEWS file has the blow-by-blow list of changes.
