To get a working copy of JuliaCall in R

#Problem I was solving:

• I was getting a SegFault Error when trying to load JuliaCall from R.
• I was also getting package not found errors from certain pkgs prescribed by my startup.jl file

Versions

R version: R version 4.0.3 (2020-10-10) Julia: I let JuliaCall install a new version of julia at this location: /Users/swojcik/Library/Application\ Support/JuliaCall/julia/v1.5.0/bin/julia

# Julia and R on Amazon EC2
#### This is basically forked from: https://github.com/magerton/ec2-for-R-and-julia

## Purpose

This guide explains how to set up a simple Amazon Linux 2 instance on EC2 for use with Julia + GPU.

The guide assumes basic familiarity with a UNIX-like systems (e.g., navigating the file structure, copying, moving, ssh, etc). Note that Windows 10 now includes the "Windows Subsytem for Linux" (WSL), which provides a very nice terminal environment ([MSDN setup guide](https://msdn.microsoft.com/en-us/commandline/wsl/install_guide)). The Git Bash terminal is also a good choice for Windows. macOS users may make use of the built-in macOS terminal.
