Setting Up Raspberry Pi Temperature/Humidity Sensors for Data Analysis in R

This tutorial is going to cover how to set up a temperature/humidity sensor with a raspberry pi. You will learn how to setup the sensor, a MYSQL server, and connect to the databse remotely in R. I will also do exploratory data analysis in R with the stored readings. A little bit of familiarity with linux, mysql servers, soldering skills, and R is...

Shiny App: Drive Time Isochrones

November 4, 2018

The Open Source Routing Machine project is an excellent resource for computing routing and travel time estimates for road networks. It is an open source library that has a demo server to run API requests to. I’ll only be using one of the services (isochrones which I’ll explain below) in this blog post. To access the API there is a wonderful R package...

Shiny Gadget: Fit Distributions

The ‘Fit Distributions’ shiny gadget allows easy automated diagnostics for fitting univariate distributions. It reads in numeric vectors in the global environment, and uses MLE to estimate the parameters of the selected distributions. The visual outputs are GOF statistics, density plot, pp-plot, and qq-plot. You can also adjust the number of bins for the histogram. It currently only supports continuous distributions. install.packages('fitur') library(fitur) library(actuar) x

Speed Up Shiny Coding with Data

Introduction In this excercise, I’m going to show how to automate some aspects of coding in shiny to speed up development. Traditionally, in user interface development, one has to explicitly type out each individual input argument. For small applications, this is justified and probably isn’t worth the time to automate the task. The first part goes over using functional programming...

Animating a Monte Carlo Simulation

Introduction Oftentimes, I run into difficulty trying to explain some of the concepts of statistical sampling with audiences that either have very limited or no understanding of statistics. Given that the majority of communication of analysis has to be digested in a 1-2 hour meeting, data visualization typically is the best route for communicating my methods. One such case is unboxing...
