+# Runs R CMD check for an R package while installing dependencies with pak.
+# https://github.com/r-lib/pak is used to install package dependencies.
+# The first command installs pak following the install instruction of package itself.
+#
+# When setting Ncpus (default=1) to a higher value, pak will download and install package in parallel.
+# pak automatically uses binary packages from the public Posit Package Manager.
+#
+# This example uses the rocker/r-base image to run the R CMD check. Any other image with R installed can be used.
+# Alternatively, the rcmdcheck package can be installed and use in replacement to `R CMD check``.
