A personal vote would be to make use of the Eclipse IDE, an IDE originally written for Java but also now being used for other languages, including C#, COBOL, and ( unless I am mistaken ) the MacroMedia "MX" product suite. Although the Eclipse IDE suffers from many of the usual problems in Java, it is a reasonable compromise. Over time, as a part of Eclipse, one is apt to build in the use of an intemediate layer based upon the use of an abstract syntax tree or stack machine to which "R" is compiled. Depending upon one preference, that layer is apt to be the Java JVM, the new Parrot virtual machine used in PERL 6, a .NET-type of approach, or ( perhaps best ) whatever Luke Tierney decides on. So you think of the script editor and IDE as also linked into the long term evolution of "R" as a language.

Something along the lines of the script editor in S-Plus. Currently Rgui can only display a file read-only in a pager. As far as I can tell there's been little motivation to implement an editor, as most developers use (the excellent) ESS, or don't use Windows. I also use ESS, but the students here are taught S-Plus and learn to use the .ssc editor. I think it would be a good selling point if the equivalent existed for R, without the need to use an external editor (or a hack in Tcl/Tk). So I'd like to write one and contribute it. I've had a quick mess with the code, and I've now got a partially usable editor working. Before I go any further and implement it fully, I just wanted to ask whether this is a desirable thing for R. In case there are long-term plans to scrap and rewrite the whole Rgui code base... Any gotchas, dos or don'ts for writing this? I suppose we'd want something like a new R function file.edit to open the file for editing, analogously to file.show which opens a text file read-only. Currently edit() can be used to invoke an editor, but that seems to be designed to work on objects rather than files.
