Absolutely - and I have also ignored the question of how the packages should
be installed - I opted for install.packages, but there is also the apt-get
way for some packages. So there is sometimes the need to add dependencies
via apt-get / synaptic, and if apt-get should be used to install the
packages, my script idea also would fail.
But when using install.packages(), it should mainly automate the task.

Rainer
