-      R also has tools for ensuring that specific packages versions can be

-      packages required for a project to a local archive as they existed at a

+      R has various tools for ensuring that specific packages versions can be
+      required for analyses. As an example, the <pkg>renv</pkg> package installs
+      packages in project-specific directory, records "snapshots" of the current
+      package versions in a "lockfile", and restores the package setup on a
+      different machine.

+    <ul>
+      <li>
+        <pkg>checkpoint</pkg>: Allows you to install packages as they existed on
+        CRAN on a specific snapshot date as if you had a CRAN time machine.
+      </li>
+      <li>
+        <pkg>groundhog</pkg>: Make R scripts that rely on packages reproducible,
+        by ensuring that every time a given script is run, the same version of
+        the used packages are loaded.
+      </li>
+      <li>
+        <pkg>liftr</pkg>: Persistent reproducible reporting by containerization
+        of R Markdown documents.
+      </li>
+      <li>
+        <pkg>miniCRAN</pkg>: Makes it possible to create an internally
+        consistent repository consisting of selected packages from CRAN-like
+        repositories.
+      </li>
+      <li>
+        <pkg>packrat</pkg>: Manage the R packages your project depends on in an
+        isolated, portable, and reproducible way.
+      </li>
+      <li>
+        <pkg>rbundler</pkg>: Manages a project-specific library for dependency
+        package installation.
+      </li>
+      <li>
+        <pkg>renv</pkg>: Create and manage project-local R libraries, save the
+        state of these libraries to a 'lockfile', and later restore your library
+        as required.
+      </li>
+      <li>
+        <pkg>switchr</pkg>: Provides an abstraction for managing, installing,
+        and switching between sets of installed R packages.
