<p>HaSa is not yet available as a CRAN package. The user needs to install it directly from its repository. Since versions of certain packages were pinned (c.f., Section 2.1), the user should use <code>upgrade = FALSE</code> when calling <code>remotes::install_git</code>. In the following example the user can install the <code>HaSa</code> R package, build its manual and its vignettes.</p>
