Posted by on Jul 30, 2014 in R blog | 1 comment

Some time ago, I was contacted from guys at Packt Publishing. Their just published the Building Interactive Graphs with ggplot2 and Shiny online course and they ask me my (humble) opinion.

Sales Dashboard in R with qplot and ggplot2 – Part 3

Posted by on May 15, 2014 in R blog | 0 comments

In Part 3 of this series we will explore some more variations to our Sales Dashboard in R and introduce new ways of visualizing sales related data with qplot and ggplot2. If you haven't done it yet, it is recommended to read Part 1 and Part 2 first. 1. Dodging (with care!) The last bar chart we created in Part 2 could be further improved to allow a year by year comparison of the orders each sales person brought in. Visually we could show the orders from each year side-by-side for each sales person. Once again, this is fairly easy to do...

Sales Dashboard in R with qplot and ggplot2 - Part 2

Posted by on May 8, 2014 in R blog | 0 comments

In Part 1 of this series we moved the first steps into building our Sales Dashboard in R. In this Part 2 we explore additional ways to display sales related data. If you haven't read Part 1, it is highly recommended that you do so first because we will build on what was covered there. 1. Bar charts A useful way to visualize the total order intake by sales person is to produce a bar chart with the total order amount for each sales person. While this is also an easy task for qplot, we have to be careful about which additional parameters are...

Sales Dashboard in R with qplot and ggplot2 - Part 1

Posted by on Apr 2, 2014 in R blog | 0 comments

In a previous post on my personal blog about creating Pivot Tables in R with melt and cast we covered a simple way to generate sales reports and summary tables from a data set consisting of orders. It is often said that a picture is worth 1000 words, so in this series of posts we will focus on how to create visual representations and summaries of the same data. Our graphical library of choice for the job will be ggplot2 (what else?), even though we are mostly going to use it in its simplest format, which is through qplot. I have written other...
