Problem

Pear is the the old PHP-packagemanager, but most 'packages' are nowadays managed with composer on base of git-repositories.
Adding pear-packages to a composer based installation is a little challenge that shall be explained below.

How to use Neovim or VIM Editor as an IDE for R

Note: This tutorial is written for Linux based systems.

Requirements

R >= 3.0.0

To install the latest version of R please flollow the download and install instructions at https://cloud.r-project.org/

Neovim >= 0.2.0

Neovim (nvim) is the continuation and extension of Vim editor with the aim to keep the good parts of Vim and add more features. In this tutorial I will be using Neovim (nvim), however, most of the steps are equally applicable to Vim also. Please follow download and installation instructions on nvim's GitHub wiki https://github.com/neovim/neovim/wiki/Installing-Neovim.

Redhawk on Raspberry Pi

One option for compiling Redhawk for the Raspberry Pi is using QEMU on a host to compile it into the image before loading on the rpi hardware - this takes advantage of the superior hardware on your host to decrease compile time. These instructions verified for host system Ubuntu 16.04, Raspberry Pi image Raspbian Stretch 2017-09-07, and Redhawk 2.0.7.

It is important to note that Redhawk is only officially supported on CentOS 6 and 7 and therefore any time you try to compile it for other OS's it's possible (likely on systems like Ubuntu/Debian) that you'll have issues with newer versions of dependencies, the most likely offenders in the past have been:

Library	CentOS 6.9	CentOS 7.4	Ubuntu 16.04	Debian 9.2	Raspbian Stretch	Fedora 28
gcc	4.4.7	4.8.5	5.4.0	6.3.0	6.3.0	8.1.1
libstdc++	4.4.7	4.8.5	5.4.0	6.3.0	6.3.0	8.1.1
