structs
provides you with data structures that are similar to
data structures commonly found in Python, Ruby, PHP, and other
scripting languages. While nearly all of the functionality provided
by structs
is possible in base R, structs
provides a similar look
and feel to other languages that many developers are more comfortable
using (list.py
, dict
). structur also provides a set of functions
to interact with these data structures. Most of the methods and functions
come directly from the Python API. For more informaiton on using structur see
below, or visit the github page.
Lists
R has it's own list structure, called list
. It's also
functions as a sort of dictionary, but it's not exactly clear (especially
for first time R users) when and where to use it. list.py
provides
a more familiar API for those of you coming from Python, Ruby, Javascript, etc. It has
an OOP feel and allows methods to be accessed via the $
operator
(similiar to . in other OOP langauges).
Dicts
dict
is similar to a Python dictionary, a Java HashMap, or a PHP array. It's
an abstraction on top of a regular R list
that functions as a basic key, value store.
Other functions
zip.tuple | similar to zip() in Python |
zip.dict | similar to dict(zip()) in Python |
is.dict | check if a data structure is a dict |
is.list.py | check if a data structure is a list |
