Parallel execution of randomForestSRC
I guess I’m the resident expert on resampling methods at work. I’ve been using bagged predictors and random forests for a while, and have recently been using the randomForestSRC (RF-SRC) package in R (http://cran.r-project.org/web/packages/randomForestSRC). This package merges the two randomForest implementations, randomForest package for reg...

Look! It’s your data!
If a picture is worth a thousand words, then how many tables are a single visualization worth? Exploratory data analysis is a great way to see what is and is not in your dataset. I work in a hospital research group. Most of my colleagues are more comfortable in SAS than in R. One of the first ideas I had to help the workflow here was to create an...

The design of the feature set is complete even if the code has some catching up to do. After the v1.1.0 release we found a bug in gg_partial when handling ...

Plus I’m presenting the regression random forest vignette to the stats group here tomorrow. http://cran.r-project.org/web/packages/ggRandomForests/index.html I’ve got another blog post percolating that will detail the biggest change in this version (improved code testing), so ...

Testing, testing, testing!
R testthat unit tests with GitHub, Travis-CI continuous integration and the covr package for Coveralls code coverage. I’ve been working pretty hard on getting the ggRandomForests package wrapped up so I can work on some other projects that have as much or more potential impact. This is my second CRAN package, and I’ve learned a lot about R pr...

From Markdown to LaTeX output using RMarkdown.
I’ve been working on the ggRandomForests vignettes pretty consistently now. I’m writing the randomForestSRC-Survival vignette in LaTeX with the knitr vignette engine. I wrote the the randomForestSRC-Regression vignette in markdown. I’ve decided to upload the Regression vignette to arXiv for additional distribution. The arXiv submission pro...
