Hi,
I am not sure if this is the right list to ask this question (though I did
not find a more appropriate one).
I've started using R a month ago, and small scripts work fine. However, when
I start writing more complex code, it gets messy.
1. Is there any way to debug "normally", with breakpoints?
The trace() function does that. setBreakpoint() is a front end for it.
One current limitation is that it only allows one breakpoint per
function; that may change soon.
2. I am using the Eclipse plugin (StatET), and tried JGR(). Is there an IDE
that enables breakpoints?
3. Is there an equivalent to "include" in other programming languages? So
many functions in one file are very messy. I would like to break it to
several files.
Write a package. It is much easier than it looks at first. Start with
package.skeleton, and follow the instructions from there.
4. Any way to create a "local" context of variables inside a function?
Otherwise I have to be careful to give different names inside functions, to
those in the workspace.
Functions always have a local context for writing. There's no simple
way to create a local context for reading.

I should point that I am a long time Matlab user and am probably expecting
some things that don't necessarily exist in R...
I know it's a lot, if there is a more appropriate forum to ask these, please
point me in that direction.
Thanks,
Eran.
