Day 07 – little helper count_na

We at STATWORX work a lot with R and we often use the same little helper functions within our projects. These functions ease our daily work life by reducing repetitive code parts or by creating overviews of our projects. At first, there was no plan to make a package, but soon I realised, that it will be much easier...

Rrrrs in R – Letter frequency in R package names

R package authors sometimes like to add the letter “r” to package names (for example, the tidyverse packages). baRcodeR also has an extra “r” at the end as well. I thought I could use some available data see if the letter frequency changes compared to the English language average. I used two data sets. The first is the percentage frequency...

Network Centrality in R: An Introduction

This is the first post of a series on the concept of “network centrality” with applications in R and the package netrankr. There is already a rudimentary tutorial for the package, but I wanted to extend it to a broader tutorial for network centrality. The main focus of the blog series will be the applications in R and conceptual considerations will only...

Intuition for principal component analysis (PCA)

Principal component analysis (PCA) is a dimension-reduction method that can be used to reduce a large set of (often correlated) variables into a smaller set of (uncorrelated) variables, called principal components, which still contain most of the information. PCA is a concept that is traditionally hard to grasp so instead of giving you the n’th … Continue reading "Intuition...

Gender Diversity in the R and Python Communities

Many (if not most) tech communities have far more representation from men than from women (and even fewer from nonbinary folk). This is a shame, because everybody uses software, and these projects would self-evidently benefit from the talent and expertise from across the entire community. Some projects are doing better than others, though, and data scientist Reshama Shaikh recently...

Extract data from a PNG/TIFF

Sometimes it’s useful to be able to extract data from a published figure. If the figure isn’t a vector based format (for which the numeric data is probably still in the file), it’s possible to digitize the image with R, click the points and extract it that way. The digitize package is simple to use
