Dear useRs: It's been some time since we last sent out an announcement, so this one will cover more than just the last update. The latest release of randomForestSRC is now available on CRAN at: https://CRAN.R-project.org/package=randomForestSRC The GitHub repository, through which we prefer to receive bug reports, is at: https://github.com/kogalur/randomForestSRC If you do find issues, please use: https://github.com/kogalur/randomForestSRC/issues and tak...

Dear useRs: The latest build of randomForestSRC (2.5.1) includes a configuration file that switches on the -fopenmp tag during compilation on systems that support OpenMP parallel processing. Previously, to achieve parallel processing, we required the additional step of executing an autoconf command before compiling and installing the package fr...

...I want to build a model for each ecozone (UK/ EC) using all species (relative abundance) as response matrix, and acoustic indices as predictors. I?d then like to know: - total variance explained & error - variable importance (stable rank at least) - proximity matrix The interface for package randomForestSRC looks hopeful. You can specify a MRF like this: > rfsrc(Multivar(y1, y2, ..., yd) ~ . , my.data, ?) So for a data matrix containing 1984 observations of 26 Acoustic indices and 65 species (UN. CG etc) - uk_ai_sp - It seems you can build a multivariate regression model like this: > uk_sp_ai...

We recently posted randomForestSRC on CRAN. It uses OpenMP in the native code extensively. We set the default number of cores to two (2), but we typically run it at the maximum (omp_get_max_threads()) during analysis. Currently, users need to set options(), set an environment variable, or edit their .Rprofile to use more than two...

Hi, I am writing this message for the benefit of the community.I have been working with randomForestSRC on a windows machine.I have been trying for days to output the forest to an rfz file so that I can print a graphical representation of the tree using Ishwaran and Kogalur's java GUI for visualizing forests at no avail.I finally contacted Dr. Kogalur who has been extremely helpful.The bottom lin...
