Yes.

And R/Python/Julia packages are always installed within the users home directory.
ℹ️ Even as root because of environment variable PIP_USER=1[^1].

[^1]: i.e. command line option --user set by default via environment variable.

To connect as root, e.g. modify the devcontainer.json for R base as follows:

diff --git a/.devcontainer/r-base/devcontainer.json b/.devcontainer/r-base/devcontainer.json
index 7f81ce2..571b9e3 100644
--- a/.devcontainer/r-base/devcontainer.json
