Whenever I have a few hours, I work on the data analysis code for the European Food Safety Authority data on mycotoxins that I have received a few months ago.
plyr and dplyr packages (dplyr is part of tidyverse) have been instrumental to get an overview of the data, answering questions like “How many samples from country X? or How many toxins analysed in sample Y…?” Basic boxplotting of subsets (e.g., from a time range, a specific country or for a specific toxin) provide a crucial overview before conducting a detailed analysis.
