R Interoperability
Paul D. McNicholas, Peter A. Tait · 2019
This chapter illustrates the interoperability between R and Julia. Considering the wide range of contributed libraries available for R, the ease with which R can be called from Julia is a significant advantage. The RDatasets.jl package provides access to some of the most commonly used R datasets. The Julia array index is actually a column in the crabs dataset, and the submitted command returns the data in the index column of the R dataset. A key feature of the Parsimonious Gaussian mixture model family is that all members have O covariance parameters, that is, the number of covariance parameters is linear in the dimensionality of the data. The random forest algorithm is implemented in the R package ranger. The ranger package is a newer implementation of random forests, optimized for speed and high-dimensional data.
