December 2, 2014
By

Since the previous post was fairly popular, I went ahead and built a small shell script (also below) to ease the process of building the OS X Shiny-gist application. After copying the script to a place you can run it from in your PATH and executing a “chmod a+x shinyapp.sh” (or whatever you named it), all you have to...

Turn R (Shiny) Scripts Into Double-clickable OS X Applications With One Line of Code

I was playing with some non-security-oriented R+Shiny code the other day, and thought that Shiny apps would be even more useful if they were double-clickable applications that you could “just run”—provided R was installed on the target system—vs have to cut/paste code into R.

October 17, 2014
By

Highcharts is the best JavaScript chart library, I feel. By default, there is an export button which can let you save the interactive figure to PNG, JPEG, PDF and SVG format, and one important point is, you can use it in your shiny app through R package rCharts. However, there are some limits in such a way, the default...

(This article was first published on Category: R | Huidong Tian's Blog, and kindly contributed to R-bloggers) It’s a common requirement that your Shiny application should be bilingual. I have tried several methods and finally I got one which is not so difficult to maintain. My idea is: Create a bilingual dictionary or a lookup table which contains three...

A month ago when the WHO was projecting estimates of the effect of current outbreak of Ebola being as deadly as affecting 20,000 people, I ran some elementary modelling and found that these estimates are far too small given the current trend.  The...

Data management with ShinyApps.io

Some of the most innovative Shiny apps share data across user sessions. Some apps share the results of one session to use in future sessions, others track user characteristics over time and make them available as part of the app. This level of sophistication creates tricky design choices when you host your app on a
