Hi, I am using the caretNWS package to train some supervised regression models (gbm, lasso, random forest and mars). The problem I have encountered started when my training data set increased in the number of predictors and the number of observations. The training data set has 347 numeric columns. The problem I have is when...

Hi, I am using caretNWS on a RHEL x86_64 system and I am getting an error message that is nearly identical to the one occuring in http://www.r-project.org/nosvn/R.check/r-release-macosx-ix86/caretNWS-00check.txt Error in socketConnection(serverHost, port = port, open = "a+b", blocking = TRUE) : unable to o...

...dually using information from the training set samples. Three vignettes come with the package and include several examples. A few example data sets, mostly from quantitative structure-activity relationship (QSAR) experiments, are also contained in the package. The other two packages, caretLSF and caretNWS, provide alternate versions of caret's train function that can be executed in parallel using the Rlsf and nws packages, respectively. For example, if bootstrapping is used to tune a model, the B models can be split over M different nodes. For caretNWS, either the free nws package or the commer...

New major versions of the caret packages (caret 3.37, caretLSF 1.23 and caretNWS 0.23) have been uploaded to CRAN. caret is a package for building and evaluating a wide variety of predictive models. There are functions for pre-processing, tuning models using resampling, visualizing the results, calculating performance and estimating variable importance. caretNWS and caretLSF...

...00 trees can often be used to get predictions for any boosted tree with less than 500 trees. The affected models are: pls, plsda, earth, rpart, gbm, gamboost, glmboost, blackboost, ctree, pam, enet and lasso. The caretLSF package is a parallel processing version of caret. The other caret package, caretNWS, will be updated to work with the new version of caret shortly.

...e computations were changed to incorporate prevalence - prevalence was added as an option to several functions - detection rate and prevalence statistics were added to confusionMatrix - the examples were expanded in the help files This version of caret will break compatibility with caretLSF and caretNWS. However, these packages will not be needed now (see above) and will be deprecated. They will work on versions of caret <= 3.51 and will not be developed going forward. However, they can still be found at fhttps://r-forge.r-project.org/projects/caret/ Send questions, comments etc to max.kuh...
