1. Windows OS: you should run source("preinst.r") first under R console. This installs all required R packages for bear. Then type library(bear) (Enter), followed by go(). There is a pop-up dialogue asking if you want to install GTK+ driver. Click 'Yes, to install GTK+ driver' menu. It's done. You only need to do this step once. After these steps, you can install bear packages from the menu of R console (install packages from a local zip file.)
2. macOS: you will need to Homebrew GTK+ driver first before running source("preinst.r"). You should have Homebrew installed on your macOS first. To install Homebrew, under the terminal program, type and run /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   (use copy-and-paste to avoid typo here; or you can google it about how to install Homebrew.) Then same in the terminal program, type and run brew install gtk+ cairo pkg-config. Sit and wait for a while. After it finishes, you can run source("preinst.r") under R console now. Unlike Windows OS, there will be no pop-up dialogue since you have already installed GTK+ driver on your macOS.Now you can install bear package now.
3. linux PC distros: the procedures are pretty same as macOS, it means that you need to install GTK+ driver first before source("preinst.r"). Here I just mention Ubuntu distro. Under the terminal program, type sudo apt-get install -y libgtk2.0-dev. Then you can run source("preinst.r") under R console now. Finally you can install bear package now. The names of GTK+ driver may differ a little bit with other distros. Let me know if you use Fedora or archlinux distros.
