[R-pkgs] randomForestSRC 1.0.0 is now available on CRAN
Dear userRs: Please find randomForestSRC 1.0.0 now available for download on CRAN. Random Forests for Survival, Regression, and Classification provides a unified treatment of Breiman's random forests (Breiman 2001) for survival, regression, and classification problems. The underlying code is based on Ishwaran and Kogalur's now retired "randomSurvivalForest" package and has been significantly refactored for improved computational speed. It implements Breiman's random forests for a variety of data settings. Numeric or categorical (factor) responses yield regression and classification forests. Survival and competing risk forests are grown when the response is right-censored. Different splitting rules invoked under deterministic or random splitting are available for all families. Variable predictiveness can be assessed using variable importance (VIMP) measures for single, as well as grouped variables. Variable selection is implemented using minimal depth variable selection. Missing data (for x-variables and y-outcomes) can be imputed on both training and test data. This package implements OpenMP shared-memory parallel programming. However, the default installation will only execute serially. To utilize OpenMP, the target system must first support it. To install the package with OpenMP compiler options turned on: (1) Download the source code for the package. (2) From the root directory of the package source run the command "autoconf". (3) Use "R CMD INSTALL" on the modified package directory. Thank you. ubk Udaya B.
