SEXP i/o, .Call(), and garbage collection.
Apologies for any obtuseness in the following. We have been working on Version 2.0 of the randomSurvivalForest CRAN package and we're encountering a perplexing 'memory not mapped' segfault that we believe is "influenced" by GC. We essentially have two R functions, rsf.default(..), and predict.rsf(..) and two corresponding entry points, rsfGrow(...), and rsfPredict(...),

randomForestSRC 2.9.0 is now available
...e G-mean, but misclassification error can be requested. Also, the new parameter get.tree in predict.rfsrc() allows users to extract the ensembles for a single tree or subset of trees over the forest. The default nodesize for survival and competing risk has been changed to 15. We've added new splitrules "auc" and "entropy" for classification. A new variable importance methodology called Holdout VIMP has been implemented. Here, we exclude a variable from a subset of trees and compare the error rates between those trees in which the variables was included against those in which i...
