Emacs vs Eclipse vs Rcmdr

Hello

 Rcmdr Pros and Cons:
 - I haven't used it for a long time, so can't really comment.
 - However, I was surprised by how many reverse dependencies it has. So
 I will assume it has some potential.

Rcmdr is probably not the best editor around. However, it is a fairly
robust and useful GUI that can be used as a menu-panel to any
underlying R terminal, including text editors that can run R (consider
using ?Commander start-up options console.output=TRUE and
prefixes=c("> ", "+ ", "", "") ).

As to the editor choice, I am currently using Geany SVN + Rcmdr (the
next Geany release will have the hidden option "send_selection_unsafe"
that allows for quick code execution when set to "true" and "Send
selection to terminal" bound to a key). Geany is a cross-platform
intuitive IDE that understands R files and has an integrated VTE
(Terminal) that can run R.

Liviu
