I like to use R for work and also during my free time.
From time to time I update my Shiny App called LabCalculateR, which offers a selection of calculation functionalities such as pipetting schemes for calibration stock solutions and other things that are done on a daily basis in the analytical chemistry lab.
I also created an R package called aquacultuR, which builds on my Aquaculture Formulary where I collect equations that are used in aquaculture research. My goal is that this package will allow to run a full-fledged analysis of data acquired during feeding trials with just one click on the knit button in RMarkdown.
