[R] R debugging options

What options are available for me to debug my R scripts? For example I 
normally do something like

>function1("height", "weight")

myfunctions.R is a large R source file that contains many functions. function1 
is the "main" function in myfunctions.R. It calls many other user-written 
functions that are also in myfunctions.R.

I only want to debug the R scripts. I do not need to get into the code of R 
itself. I would like to be able to:

- see the source as I am debugging
- execute line-by-line
- see and modify variables
- have the option to either descend into function calls, or not
- have the option to either descend into loops, or not

Maybe this is asking too much but I thought I would lay out my dreams and then 
you can tell me what is really possible.
