1.0.1: Initial version to CRAN 1.0.2: Formatting changes to make documentation look better. 1.0.3: Updated author list, added labelswapprob option and extra checking of user input to create.data(). 1.1.0: Added opt.nested.crossval and opt.splitval functions. 1.1.1: Implemented uninformative censoring in create.data. 1.1.2: bugfixes for parallelized opt.nested.crossval + Elastic Net combination 1.1.3: Changed opt1D and opt.nested.crossval examples to use less system resources. 1.1.4: Fixed opt.nested.crossval and opt.splitval when using unpenalized covariates, added more examples to opt.nested.crossval, added citations to published paper. Made it so a broken rlecuyer installation causes a warning instead of an error. 1.2.1: Added package Vignette. 1.2.2: Added cl as an optional parameter, to allow the user to set up the snow cluster. 1.2.3: Created proper NAMESPACE and cleaned up thereby unneeded library() calls. Note that rlecuyer has no NAMESPACE so still relies on library calls. 1.2.4: Fixed bug that occurred when the model had an intercept (non-survival models). 1.2.5: Fixed new problems introduced by imports in NAMESPACE, added tests of opt.nested.crossval(). 1.2.8: Vignette to new location, migrate from snow to parallel, misc fixes to documentation.
