Description: parses R dataset (.rda) files
The common way of reading an R dataset consists on two steps:
.
* First, the file is parsed using the function parse_file. This provides
a literal description of the file contents as a hierarchy of Python
objects representing the basic R objects. This step is unambiguous
and always the same.
* Then, each object must be converted to an appropriate Python
object. In this step there are several choices on which Python type
is the most appropriate as the conversion for a given R object. Thus,
we provide a default convert routine, which tries to select Python
objects that preserve most information of the original R object. For
custom R classes, it is also possible to specify conversion routines
to Python objects.
.
The basic convert routine only constructs a SimpleConverter objects and
calls its convert method. All arguments of convert are directly passed
to the SimpleConverter initialization method.
.
It is possible, although not trivial, to make a custom Converter object
to change the way in which the basic R objects are transformed to
Python objects. However, a more common situation is that one does not
want to change how basic R objects are converted, but instead wants
to provide conversions for specific R classes. This can be done by
passing a dictionary to the SimpleConverter initialization method,
containing as keys the names of R classes and as values, callables
that convert a R object of that class to a Python object. By default,
the dictionary used is DEFAULT_CLASS_MAP, which can convert commonly
used R classes such as data.frame and factor.
