Here is a presentation of mashing techniques and a short experiment for Dr. Tenjo’s Fermentation class.

An overview of how to work with Rasters in R.

A population graph is a network structure based upon inter-stratum conditional genetic covariance (see Dyer & Nason 2004 for a more complete discussion). In this context, it is often of interest to know the statistical stability of your loci in determining the topology you see in the popgraph. Here is a way to subsample the loci you have and identify the extent to which you are asymptotically estimating a stable topology.

The solution to this, is to recognize that a lot of the content I make (in fact most of it) will be presented as output from R Markdown. The tutorials I create, the analyses I do, etc. As such, why not start with an R Markdown file in the first place and go from there? Enter blogdown devtools::install_github("rstudio/blogdown") I then had to install python3 and pip to get the academic Hugo theme going.

The gstudio package has routines that can be used to simulate random populations. I’ve added these to facilitate more exploratory data analysis. Here is how you can use them. If you have not updated the gstudio and popgraph packages in a while, you probably should. Here is how (if it asks if you would like to update the other packages, it is probably a good idea to say yes).
