ROC curve in randomSurvivalForest
I'm using randomSurvivalForest to predict survival from a rather small
sample. As it's not enough data to have training and validation set, I
rely on the "Estimate of error rate" computed by the randomForest. If I
understand the method correctly, it repeatedly partitions the data into
varying training/validatio...

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(...), into our C lib...

Random Survival Forest 1.0.0 is now available.
Dear useRs,
Release 1.0.0 of the new R package 'randomSurvivalForest' is now available
on CRAN and its mirrors. The package implements Ishwaran and Kogalur's
Random Survival Forests algorithm for right censored survival data. The
algorithm is closely patterned after Breiman's random forests, but suitably
modified for the survival setting. Some key fea...

Obtener las reglas de un árbol de decisión
Hola,
Me gustaría obtener las reglas que genero con un árbol de decicisión
creado con party. Algo parecido a lo que realiza esta función con rpart
http://www.togaware.com/datamining/survivor/Convert_Tree.html la idea es
disponer de esas reglas en un fichero de texto.
En general si alguien sabe de algún paquete que permita obtener el código
que genera la puntuación, el "score" para un
