About the Project

A data frame is a two dimensional data structure structure whose columns may be of differing types. It is similar to, and may be manipulated as, a Common Lisp array. Data frames hold tightly coupled collections of variables that all belong to one experiment.

Built With

Getting Started

To get a local copy up and running follow these steps:


An ANSI Common Lisp implementation. Developed and tested with SBCL.


Lisp-Stat is composed of several system that are designed to be independently useful. So you can, for example, use data-frame for any project needing to manipulate two dimensional data in a machine learning or statistical setting.

Getting the source

To make the system accessible to ASDF (a build facility, similar to make in the C world), clone the repository in a directory ASDF knows about. By default the common-lisp directory in your home directory is known. Create this if it doesn't already exist and then:

  1. Clone the repositories
cd ~/common-lisp && \
git clone && \
git clone
  1. Reset the ASDF source-registry to find the new system (from the REPL)
  2. Load the system
    (asdf:load-system :data-frame)

If you have installed the slime ASDF extensions, you can invoke this with a comma (',') from the slime REPL in emacs.

Getting dependencies

To get the third party systems that Lisp-Stat depends on you can use a dependency manager, such as Quicklisp or CLPM Once installed, get the dependencies with either of:

(clpm-client:sync :sources "clpi") ;sources may vary
(ql:quickload :data-frame)

You need do this only once. After obtaining the dependencies, you can load the system with ASDF as described above without first syncing sources.


Create a data frame:

(make-df '(:a :b) '(#(1 2 3) #(10 20 30)))

For more examples, please refer to the Documentation.


See the open issues for a list of proposed features (and known issues).


This system is part of the Lisp-Stat project; that should be your first stop for information. Also see the resources and community page for more information.
