You also want to make sure the package library is specific to the minor version of R.

This makes it easy to re-install R if needed without touching your CRAN packages. I suggest you keep the packages R comes with (base and recommended) packages separate from the rest of your packages. While it may work some (even most) of the time, R-core does not guarantee compatibility between these versions and things could break (even break silently). In the class, I will use RStudio.You may see some suggestions that you can just copy your packages even when the ‘minor’ version changes. You are free to use the editor of your choice. Optionally, there is a number of other text editors, which can be associated with R, e.g. The workaround is to open the original R drawing panel - just type windows () into the console, and new active window will open (you can move it around the screen, or right-click on it by mouse and select “Stay on top” to keep it as the top window always visible on your screen).

One thing I found a bit not handy is RStudio's native graphical output - it offers its own unique sizeable graphical output into one of the subpanels (usually the bottom-right one), but it sometimes produces troubles (especially in case when you draw more complex figures).

RStudio is a convenient software, which combines R program with text editor and graphical user interface (and offers much more, like organization of scripts and outputs into a projects within single folder, and for advanced users also convenient building of packages, document markup etc.). If you already have RStudio installed in your computer, please check whether you have the latest version and update if you don't (in RStudio menu, go to Help > Check for Updates). Download the latest version from RStudio website you will need Desktop version, Open Source Edition for your system you may click here to get directly to the selection of actual RStudion version.
