A texteditor for R

I’ve been using RWinEdt for the last few years for all my R coding. But it no longer works with WinEdt 6.0 and no update has been forthcoming.

One of my readers asked two weeks ago how to control two graphics windows with the slider in gWidgets. Here is a simple example: if (!require("gWidgetsRGtk2")) install.packages("gWidgetsRGtk2") library(gWidgetsRGtk2) options(guiToolkit = "RGtk2") graphics.off() x11() x11() dev.set() gslider(from = 1, to = 100, value = 10,     container = gwindow("Two Plotting Windows"), handler = function(h, ...) {

What is wrong with this graph?

This is a graph from our surveys with the University of Munich in B&H about ten years ago.(Click on it to see a large version.)
