R help - Mar 2013 - Editing figure without re-running the plotting code?

Dear all,

I am curious if anyone knows of a command/program that would enable one to
edit a figure in R once it is created (akin to Matlab).  Currently, if I
need to make any changes to the figure I do so and then have to run the
plotting portion of the code again.  I have searched the R site mailing
lists, etc to no avail.  Any help is greatly appreciated.

Kind regards,

Sherri

The normal method is to rerun the code. If you use the ggplot2 library you can
store plots in variables and modify them, but you still have to print them again
when you want to see the results.

Hi Sherri,
As Jeff has pointed out, graphics devices in R are almost entirely 
cumulative in operation. You can display something, then add something 
else, but you don't have a buffer for the various objects in a complex 
plot that allows those objects to be altered or deleted.

The playwith package would probably allow you to do what you want, but 
there is a certain amount of learning necessary and you have to navigate 
the complexity that is hidden in most interactive plotting packages. 
That said, if you have to do a lot of this, it is worth the effort.

What most of us do is to build plots up as scripts in an external editor 
and then "source" the scripts. You can make incremental changes and
the
new plot just pops up when you source the code.
