Installing ImageMagick

[aaronxsu]

I took the following steps on Mac:

1. Open the terminal
2. Paste the following command to the terminal to install home brew, the package manager for mac:
   /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
3. After installing home brew, in the terminal, paste the following to install imagemagick:
   brew install imagemagick

Homebrew: https://brew.sh/
Mac package search for home brew: http://braumeister.org/
ImageMagick: http://www.imagemagick.org/script/index.php

If you are using linux, the installation should be similar.

If the terminal wants you to type in the password, it should be the password for system login.
When typing the password, you may not see the new character input in the terminal, but just trust the terminal and keep on typing - press enter when you finish.

Of note: you should be able to run a command line command from the R console with the following construction.

system("[insert command]")

If someone can provide guidance on a PC, that would be fantastic!

For a PC I followed the suggestions here! http://stackoverflow.com/questions/17570082/imagemagick-in-r but I found that the 64 bit version was too new for my laptop so I downloaded the Win32 version here http://www.imagemagick.org/script/binary-releases.php#windows and ran it and had it replace all the files. Then I made sure that I installed the package magick. After that I restarted R and everything ran fine. That may have overcomplicated it, but it's working so I'll take it

I found another workaround. You must click a box in the installation process that installs the legacy components (including the convert.exe). If you do this, all will be well (at least it was for me).
