NSCB Sexy Stats Version 2

October 25, 2012

(This article was first published on Data Analysis and Visualization in R, and kindly contributed to R-bloggers)

This was a revised version of my previous post about the NSCB article. With the suggestion from Tal Galili, below were the new pie charts and the R codes to produce these plots by directly scrapping the data from the webpage using XML and RColorBrewer pagkage.

Unemployment by Age Group

Unemployment by Gender

Unemployment by Civil Status

Unemployment by Educational Level
