This efficiently solves the first part of my question. I will probably
content myself with issuing this command each time I update one of the
"twocolumns"; I'm still curious whether R can store this function in
the third column, and autoupdate it whenever one of the "twocolumns"
gets modified (behaviour very similar to that of spreadsheets),
although I'd doubt R could.

Thank you
Liviu
