Fun With Plotly


From Len Kiefer: “Plotly enables you to make interactive htlm widgets that you can embed in your webpage or view from within R. I’ve been having a lot of fun converting existing visualizations I have made with ggplot2 into plotly visualizations using ggplotly…. I’m going to include the code and discussion for several graphs I’ve been using. I will use updated data that we used in our Cross talk dashboard. … Continue Reading

R for Excel Users

/ /

This post covers the why and how to switch from Excel to R for managing data and undertaking analysis. It covers the following topics: Four Fundamental Differences Between R and Excel Example: Joining two tables together Interation Generalizing through functions “Excel users have a strong mental model of how data analysis works, and this makes learning to program more difficult. However, learning to program will allow you to do things … Continue Reading

Getting Started with tidyverse in R

/ /

From Storybench: “The tidyverse is a collection of R packages developed by RStudio’s chief scientist Hadley Wickham. These packages work well together as part of a larger data analysis pipeline. To learn more about these tools and how they work together, read R for data science…. The following tutorial will introduce some basic functions in tidyverse for structuring and analyzing datasets.”

Neural Networks from Scratch (in R)


From Medium: This tutorial: “is for those of you with a statistics/econometrics background but not necessarily a machine-learning one and for those of you who want some guidance in building a neural-network from scratch in R to better understand how everything fits (and how i doesn’t).” The author’s motivations for writing the tutorial are: “Understanding (by writing from scratch) the leaky abstractions behind neural-networks dramatically shifted my focus to elements … Continue Reading

Emulating R plots in Python


This tutorial covers the equivalent plotting commands in R and Python, with the goal of replicating R plots in Python: “Some commands can be straightforward replicated in Python, some are surprisingly hard to find equivalents without using custom functions etc.” The tutorial includes: Residual plots QQ plots Scale-location plots Leverage plots

From Quick-R: “R is an elegant and comprehensive statistical and graphical programming language. Unfortunately, it can also have a steep learning curve. I created this website for both current R users, and experienced users of other statistical packages…who would like to transition into R. My goal is to help you quickly access this language in your work. I assume that you are already familiar with the statistical methods covered and … Continue Reading
