Last week, practical statistics met to discuss all things ANOVA. Below you will find the slides from my talk, but read on if you would like to learn all about ANOVA. When ANOVA is used and who uses it? ANOVA is used far and wide by the scientific community and beyond. Unfortunately, scientists also frequently misuse ANOVA. A study by Wu et al. (2011) showed that from a survey of 10 leading Chinese medical journals in 2008, 446 articles used ANOVA, and of those articles, 59% of them used ANOVA incorrectly.
superheat 0.1.0 is now available on CRAN. Superheat makes it easy to create extendable, cutomizable, and most importantly, beautiful heatmaps. It has increased flexibility and user-friendliness when compared to alternatives such as heatmap() and pheatmap(). For usage options see the vignette and for examples see the accompanying paper by Barter and Yu (2017). You can install the latest version with: install.packages("superheat") Stay tuned for new versions with added features and minor usability tweaks.
This week I was asked to give a presentation on giving presentations. So meta. Anyway, my lack of desire to spend time writing something that may have already been written by someone else led me to find a number of existing slides written by others with the same goal: to present on presenting. The only problem was that although these slides all contained excellent tips on making and subsequently presenting talks, the slides themselves were perfect examples of what not to do when making slides; they were insurmountable walls of text.
