ibawds provides useful functions and datasets for theData Sciencecourse atIBAW.

You can install the released version of ibawds fromCRAN with:

install.packages("ibawds")

And the development version fromGitHub with:

# install.packages("devtools")devtools::install_github("stibu81/ibawds")

Windows and Mac Users can download the installer for their operatingsystem fromhttps://cran.r-project.org/. For Windows, installationshould be possible also for non-admin users. Mac users may also need toinstallXQuartz.

Linux users find instructions for installation under Debian,Fedora/Redhat, and Ubuntu under the same link. Note that the officialpackage sources may contain an outdated version of R, but usually thecurrent version can be installed from some other source. Make sure thatyou install version 4.0 or newer.

We will use RStudio as ourIDEin the course. You can download it from thislink. Usually, it iseasiest to use the installer for your operating system. However, if youdon’t have admin access on your computer, you should instead downloadthe appropriate zip-file / tarball. Under Windows, extract the zip-fileto a folder where you have write access. The executable file is locatedunderbin/rstudio.exe.

When you run RStudio for the first time, you have to select the Rversion that you want to use. Usually, the dialogue box should listavailable R versions for you to choose. If not, click on “Browse…” andnavigate to the folder where you installed R.

We will use a variety of R Packages during the course. To set them up,first install ibawds with

install.packages("ibawds")

and then run the following to install additional packages:

library(ibawds)install_ibawds()

You will be asked to install missing packages. Confirm to install them.Note that this may take more than 30 minutes depending on your systemand configuration.

In order to check that everything is set up correctly for the course,run the following command:

check_ibawds_setup()

The function verifies that

• R and RStudio are up to date,
• the ibawds package is up to date, and
• all the required packages are installed

The function must be run from RStudio in order to run properly. Ifeverything is set up correctly, you will see a message that confirmsthat your system is ready for the course similar to this one:
