Why I chose MDI during R installation

When installing R on a machine that is shared among several users, some of which are accustomed to the Mac OS, I had to choose between the Multiple Document Interface (MDI) and the Single Document Interface (SDI). The MDI article on Wikipedia pointed out that the MDI interface relates all documents to a common menu bar, which is what Mac users are accustomed to; Windows users probably have encountered both, since Office applications have used at times (depending on the generation) SDI and MDI. Therefore, to make the experience less alien for Mac users on a Windows machine, I installed R configured to use MDI.
