Hook into Rgui console?

Question

Is it possible to change the behaviour of R console such that, for instance

• before each command execution a fortune() is printed, or
• similar to browser() , the prompt is altered, and some new commands (c,n,Q) are introduced?

I am looking for an alternative to readline() that keeps the history function (key up) intact.

I am using R on winxp with Rgui, but a portable solution would be great.

是的，尽管它独立于GUI，因为它仅使用回调机制，例如在R的问题中：在R命令行中显示时间时钟 。
