Requal for Windows
To use Requal, you need to have the R language installed and running on your machine. You will also need a web browser with JavaScript support (i.e. any of the standard browsers like Firefox, Chrome, or Safari). Requal can be installed in two ways - via the R console or RStudio. For inexperienced users, we recommend using RStudio.
Step one. Instal R. Go to https://cran.r-project.org/bin/windows/base/ and click on Download R for Windows. Download the file and run it.
During installation you can agree with all default options or customise the installation according to your needs.
Step two. Install RStudio. Go to www.rstudio.com and download a free desktop version.
Once downloaded, install Rstudio and launch it.
Step three. Install Requal. Go to https://github.com/RE-QDA/requal/releases Click on the newest release (1.1.2) and then scroll down at the bottom of the table, and download the compressed package, e.g. requal_1.1.2.9002.tar.gz
In the RStudio console, install the remotes package by running install.packages("remotes") command.
Next, install the Requal package by running remotes::install_local(file.choose()) and selecting the downloaded release file on your hard-drive.
If you are asked to update packages, update All (enter 1).
The installation may take a few minutes as it is necessary to download and install several packages. After the installation, the last line reads: * DONE (requal)
Step four. Launch Requal from the RStudio console with the following command: requal::run_app(options = list("launch.browser"))
Step one. Instal R. Go to https://cran.r-project.org/bin/windows/base/ and click on Download R for Windows. Download the file and run it.

If the installation via remotes does not work, install a development version via devtools and than reinstal Requal with install.packages(file.choose()).
