Package FAQ
What are packages ?
\(R\) packages are collections of functions and data sets (just files) developed by the community (or you). They increase the power of \(R\) by improving existing base \(R\) functionalities, or by adding new ones.
When you download \(R\) you are only getting the bare-bones, most basic files. This is nice, as it keeps the program from hogging your entire hard drive, but doesn't offer much in terms of data anaysis. Today there are over 10,000 packages available on \(CRAN\) alone, so downloading all of them would be silly and probably fill your computer several times over. Individual users are left with the freedom to choose which packages they need.
Installing packages
Installing is the act of getting the package files onto your computer and stored in a location on your hard drive where \(R\) can find them. Usually the files are zipped/compress and must be extracted/unpacked. The directions below will walk you through the automated process of using the user interface in \(R Studio\) (rather than actual syntax).
In R Studio:
- Click on the Packages tab in the panel with the most tabs
- Click on the word Install just under and to the left of the tab
- In the box labelled "Packages", type the name of the package you would like to download. You can do several at once, just seperate them with at least one space or a comma.
You only need to INSTALL packages ONCE per computer.
Leave the installation "library path" as the default. Also, make sure the box for "Installing dependencies" box is checked.
? You can copy-and-paste the following list into the box (labeled 3 above) to load the packages that we find most commonly used. You can install more packages at any time.

When you click the Install buttom, a smaller window may asks if you would like to "re-start \(R\) prior to installing," choose "no" and manually close and open the \(R Studio\) program once all packages have been downloaded, unpacked, and checked (saves time). This may take a few minutes, especially if you have selected multiple packages.

-
the exam or tutorial questions (answers remaining hidden) as a PDF or HTML file.
-
the exam or tutorial questions with sample answers as a PDF or HTML file.
In addition, you will be able to:
-
Create coloured boxes to highlight some markdown or R content.
-
Create examination papers with
- multiple choice questions
- a candidate identification form
- dotted lines placeholders to fill in answers
-
Create a new \(R Markdown\) file with solution chunks replaced by empty ones.
devtools:: install_github("koncina/unilur") Prepare APA journal articles with \(R Markdown\)
papaja is a \(R\) package in the making including a \(R Markdown\) template that can be used with (or without) \(R\) Studio to produce documents, which conform to the American Psychological Association (APA) manuscript guidelines (6th Edition). The package uses the \(LaTeX\) document class apa6 and a .docx-reference file, so you can create PDF documents, or Word documents if you have to. Moreover, papaja supplies \(R\) functions that facilitate reporting results of your analyses in accordance with APA guidelines.
papaja has not yet been submitted to \(CRAN\) because it is under active development. Currently, there are still a couple of loose ends they would like to tie up before we release the package to a larger audience. There are two versions you can install from the \(GitHub\) website.
# Install the stable development verions from GitHub devtools:: install_github("crsh/papaja") # Install the latest development snapshot from GitHub devtools:: install_github("crsh/papaja@devel") Source: https://cehs-research.github.io/eBook_install/install-packages.html
