Advanced Data Operations

by Max De Wilde Ruben Verborgh | October 2013 | Open Source

In this article by Max De Wilde and Ruben Verborgh, the authors of the book Using OpenRefine, we dive deeper into dataset repair, demonstrating some of the more sophisticated data operations OpenRefine has to offer.

The true power of OpenRefine only emerges when you dive into its more advanced features. This article will therefore shed light on the following:

  • Recipe 1 – handling multi-valued cells

Adjusting Key Parameters in R

by Hrishi V. Mittal | January 2011 | Open Source

The R base library has very powerful graphical capabilities. While you can produce pretty much any type of graph with a couple of lines of code, the default layout and look of the graph is often very basic. Sometimes, you may run into problems such as axis labels and titles getting chopped off at the edges or the legend size or position may mask part of your graph. Sometimes, the default color combinations may not be suitable for presentation or publication.

In this article by Hrishi V. Mittal, author of R Graph Cookbook, we will cover:

  • Setting colors of points, lines, and bars
  • Setting plot background colors
  • Setting colors for text elements: axis annotations, labels, plot titles, and legends
  • Choosing color combinations and palettes
  • Setting fonts for annotations and titles

Let’s get started!

Adding Worksheets and Resources with Moodle

by Mary Cooch | March 2009 | e-Learning Moodle Open Source

In this article by Mary Cooch, we will learn how to save energy. Not only our own, but the world's too! Moodle's main attraction, to many teachers, is the fact that you can upload all of those worksheets that you hand out in class (and that your students lose). When you've done it once, they are there for as long as you need them—so you don't have to find and print them off the next time you do that topic, and fewer trees will be felled in the name of education!
In this article, we shall:

 

  • Put an information sheet about the River Thames into Moodle
  • Load a whole week's slideshows about River processes into Moodle in a neat folder
  • Make a click here type link (this is known as a hyperlink) to the River Thames web site
  • Create a worksheet about flooding by typing it straight into Moodle
  • Make our page a bit prettier now that we've got some real stuff on it
