[quote]1. 如在编辑一个程序时出错,则不能运行。修改保存后也是如此,必须在编辑模式下的编辑菜单中选择运行一切后,通过检查后才能执行。 这种比较麻烦,而MATLAB中保存后即可直接运行, 有无其它方法解决此问题。
[/quote]not completely understand what you are saying... but keep in mind that you need to edit programs in the memory. simply editting the file but not reading it into memory will not work. (read help on source(), or simply copy&paste ). function name doesn't need to be file name, as is in matlab. you might like matlab way of getting it done, but i don't think this is a disadvantage of R.
[quote]2. 关于重复前面的命令。只能一个一个往前翻,而MATLAB中如果你在前面第10个命令使用如abcdef,则你输入abc后再按前翻命令,很快可以调出abcdef. 有无其它方法解决这个问题。
[/quote]I don't think R can do this currently. But you can request this function for future releases at r-project.org.

关于R运行平台问题有四个(参考上海师范大学的汤银才老师的PPT)
1. R_GUI
2. R_Commander
3. R_WinEdt
4. R_ESS+XEmacs
后面三个都是需要下载数据包安装的,是否有冲突,有没有人都安装过。或能简单介绍后三个的特点及使用的注意事项。[/quote]personally, i didn't find any of them is much more better than Rterm plus one of your mostly often used editor.
[quote]关于程序调试问题:
请问下有没有设置断点,查看变量等功能,如何来查看?

last bit of suggestion: please read R_intro first. It will save you a lot of time in the long run.
