A Shiny App for Exploring Commodities Prices and Economic Indicators, via Quandl
In a previous post, we created an R Notebook to explore the relationship between the copper/gold price ratio and 10-year Treasury yields (if you’re curious why we might care about this relationship, have a quick look at that previous post), relying on data from Quandl. Today, we’ll create a Shiny app that lets users choose which different com...

What is the tidyverse?
Last week, I had the opportunity to talk to a group of Master’s level Statistics and Business Analytics students at Cal State East Bay about R and Data Science. Many in my audience were adult students coming back to school with job experience writing code in Java, Python and SAS. It was a pretty sophisticated crowd, but not surprisingly, their ...

Mapping Quandl Data with Shiny
Today, we are going to wrap our previously built Quandl/world map Notebook into an interactive Shiny app that lets users choose both a country and a data set for display. As usual, we did a lot of the heavy lifting in the Notebook to make our work more reproducible and our app more performant. The final app is available here. Devotees of this Rep...

Printing From Flex Dashboard
Shiny applications of all stripes (including flexdashboard with runtime Shiny) are revolutionary in that they put the power of R directly in the end user’s hands without needing to interact directly with the language. A common way end-users wish to interact with their data is via a dashboard that they can manipulate on the fly. Flexdashboard st...

Introduction to Volatility
This is the beginning of a series on portfolio volatility, variance, and standard deviation. I realize that it’s a lot more fun to fantasize about analyzing stock returns, which is why television shows and websites constantly update the daily market returns and give them snazzy green and red colors. But good ol’ volatility is quite important ...

In a rather low-key blog post at the end of last month, the R Consortium’s technical committee, the Infrastructure Steering Committee (ISC), launched its prototype survey of R users. The idea is to use the information gleaned from the exploratory questions in this...
