1 . Mapping with R
Following the first session about mapping with R I would like to propose you two exercises:
1) Plot a map of the world that presents information on the number of earthquakes around the world (by country)

Hint: The Significant Earthquake Database contains information on destructive earthquakes from 2150 B.C. to the present
2) Plot a map of Spain that shows any socio-economic variable by province (eg. population)

Hint:  You can find Spanish map files and data at Instituto Nacional de Estadística.
2. Data mining
After reading Development of Arab Water Sustainability Index …

The final project for the Advanced Quantitative Data Analysis course consists in a multidimensional analysis of nuclear energy around the world. Some question you may try to ask are:

is it safe?
is it clean?
is it cheap?
is it fair?

You may find inspiration for a discussed analysis in the Statistical Analysis and Visualization of the Drug War in Mexico by Diego Valle.

1. Choropleth map in R challenge
After FlowingData published an article on how to make a choropleth map (a map with regions shaded by values of a measurement variable) using Python, people at Revolutions launched a choropleth map in R challenge.

In less than 24 hours, no less than 5 hackers responded with complete solutions for plotting the US unemployment data on a color-coded map, each in less than 20 lines of R code.  Overall, the results were very close to the FlowingData original.
R graphics guru Hadley Wickham was first …

A primary way that biologists interact with their data is through visualization systems, ranging from simple, stand-alone methods to complex, integrated software packages. However, the sheer volume and diversity of both data and of visualization systems presents an increasing challenge for biologists.
The goal of this workshop is to bring together, for the first time, researchers developing and using systems to visualize a broad range of biological data, including sequences, genomes, phylogenies, macromolecular structures, systems biology, microscopy, and magnetic resonance imaging. In selecting topics for this workshop, we have focused on …

Current access to the biological databases is commonly done through the web. Usually, the different search interfaces present results as lists of entities that correspond to a search query, with links to both the entry and entries in related databases. In this work we offer a visual approach to navigate subsets of the searched data. Exploiting the network-structure of data resources, we can search, retrieve and visualize multiple data related to a given query. We will present different case studies that show the feasibility and advantages of this approach.
