Recently I have started to learn Julia but over the last few years I have programmed pretty much exclusively in R (previously it was predominantly Fortran and matlab). I have written a couple of R packages, microPop and stagePop, described in links below and I have also added some general R programming pages (e.g. on using ggplot2 and igraph) in case they are of use.

For more software see my gituhb repo

R packages

• microPop for modelling microbial populations and communities.
• I have also developed a R Shiny App to visualize the microbial networks contained in microPop.
• stagePop for modelling stage structured populations (time-delay ODEs).
• PCN for modelling potato cyst nematodes

Some presentations on programming in R:

• Brief Intro to ggplot2 (html) (and the R markdown file)
• Brief Intro to igraph (html) (and the R markdown file)
• Using latex syntax in R (html) (and the R markdown file)
• Writing an R-package
• Writing Tests (by David Nutter)
