rtemis Machine Learning and Visualization

A platform for advanced Machine Learning research and applications.
The goal of rtemis is to make data science efficient and accessible with no compromise on flexibility.

Documentation

Requirements

R version 4.1 or higher

Installation

You can install rtemis from r-universe or using pak, remotes, or devtools.

  • r-universe:

    install.packages('rtemis', repos = c('https://egenn.r-universe.dev', 'https://cloud.r-project.org'))

  • pak:

    pak::pkg_install("egenn/rtemis")

  • remotes:

    remotes::install_github("egenn/rtemis")

  • devtools:

    devtools::install_github("egenn/rtemis")

Note about Fortran support in MacOS

To allow compilation from source of any dependencies that require Fortran, you
will need to install the GNU Fortran compiler. The easiest way to do this is
with Homebrew:

brew install gcc

Then, you will need to add the following to your ~/.R/Makevars file:

FC      = usr/local/opt/gcc/bin/gfortran
F77     = /usr/local/opt/gcc/bin/gfortran
FLIBS   = -L/usr/local/opt/gcc/lib

Note about using d_UMAP()

d_UMAP() requires the uwot package, which currently requires that the Matrix and
irlba dependencies be installed from source. See more in the uwot issue
here.

More setup info

See here for more setup and
installation instructions.

Note: Make sure to keep your installation updated by running
remotes::install_github("egenn/rtemis") regularly: it will only proceed if
there are updates available.

30-second intro to rtemis

Install dependencies if they are not already installed:

packages <- c("future.apply", "ranger")
.add <- !packages %in% installed.packages()
install.packages(packages[.add])

Get cross-validated random forest performance on the iris dataset:

library(rtemis)
mod <- train_cv(iris)

What’s new

We are working towards the 1.0 release, which will feature updates to the
API as well as the backend, and preparing for CRAN submission.
This will be accompanied by expansion of the documentation.
For all updates, please see the NEWS file.

The Python and Julia ports, rtemispy and Rtemis.jl, which are not yet
publicly available, are in parallel development. With the upcoming 1.0 release
of rtemis, the aim is to offer a unified API across all three languages.

rtemislive

rtemislive is rtemis’ web interface / GUI.
It makes advanced visualization and modeling instantly accessible by all.
It is currently available for beta testing at UCSF,
and will be made publicly available once funding is secured for a hosting server.

Get the rtemis-dark VS Code theme.

Recommended font is Fira Code with its pretty ligatures.

Python & Julia APIs

Python and Julia APIs are in development. The goal is to delliver a unified API across
all three languages by the time of the 1.0 release.
