At last, since it's been like ages, I decided to put out a new version of DataMatrix. For those who haven't seen my previous post, DataMatrix is a Pythonic implementation of [R's data.frame](http://stat.ethz.ch/R-manual/R-patched/library/base/html/data.frame.html). It enables you to manipulate a text file by columns or rows, to your liking, using a dictionary-like syntax.
|
|
|
|
In this new version there have been a few improvements and correction to a couple bugs (for example saveMatrix did not really save) and the start (only a stub at the moment) of an append function to add more columns (I'll also think about a function to add rows).
|
|
|
|
DataMatrix is licensed under the GNU GPL, version 2 only. You can download [the installer]({{ site.url }}/files/datamatrix-0.5.win32.exe) (Windows) or [the source distribution]({{ site.url }}/files/datamatrix-0.5.tar.gz) (Linux and other *nixes). The only requirement is Python 2.5 or later installed on your system.
|
|
|
|
The README currently is a stub, but you can [browse the pydoc generated documentation]({{ site.url }}/files/datamatrix.html), which details how to instantiate and use DataMatrix objects (or [you can turn to my older post]({{ site.url }}/2008/06/dataframes-in-python-datamatrix)).
|
|
|
|
Also, since git is the new "cool feature of the day", DataMatrix is is hosted on github's repository, and you can grab the source with
|
|
|
|
{% highlight cpp %}
|
|
git clone git://github.com/cswegger/datamatrix.git
|
|
{% endhighlight %}
|
|
|
|
Comments and suggestions are welcome. I'll be putting a static page on DataMatrix tomorrow, if time permits.
