A chaining R executing object.

RExec lets you run R code and get the results from Python. For the most part, the interface is pretty hacky. The goal is to make it easy to automate the usage of existing R files, rather than make elegant programs integrating R and Python. (For the latter, you might consider rpy or rpy2.)

An RExec object takes a directory where it will be run. You can then add R code to the object in a variety of ways (append_string, append_file and so on). When you are done appending to the RExec object, you can use the execute() method which will run an R slave process on all of the R that you have appended so far (concatenated together. Finally, you can get access to results of your R script in a relatively unorthodox way. Any files output with an “r_” prefix will be available by calling get_text() or get_graphic() as appropriate.

RExec has a chaining interface. This means you can do things like:

r_ex =(RExec(some_dir)
       .append_file("some.R")
       .append_file("other.R")
       .execute())
r_ex.get_graphic('foo.svg', path='absolute')
