Overview

About

Maintained by Spencer AielloCRAN page ↗GitHub ↗

Provides a full implementation of the 'Jupyter' http://jupyter.org/ messaging protocol in C++ by leveraging 'Rcpp' and 'Xeus' https://github.com/QuantStack/xeus. 'Jupyter' supplies an interactive computing environment and a messaging protocol defined over 'ZeroMQ' for multiple programming languages. This package implements the 'Jupyter' kernel interface so that 'R' is exposed to this interactive computing environment. 'ZeroMQ' functionality is provided by the 'pbdZMQ' package. 'Xeus' is a C++ library that facilitates the implementation of kernels for 'Jupyter'. Additionally, 'Xeus' provides an interface to libraries that exist in the 'Jupyter' ecosystem for building widgets, plotting, and more https://blog.jupyter.org/interactive-workflows-for-c-with-jupyter-fe9b54227d92. 'JuniperKernel' uses 'Xeus' as a library for the 'Jupyter' messaging protocol.

Changes in 1.4.1.0

PATCHES

1. Build a windows interrupt handler that will listen to a Windows Event set by a parent process.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/JuniperKernel/JuniperKernel_1.4.1.0.tar.gz"
pkgFile <- "JuniperKernel_1.4.1.0.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (1.4.1.0) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("JuniperKernel/JuniperKernel")

Development version from JuniperKernel/JuniperKernel. Installs pak first if it is not already available.
