Using the R scan function to read non-rectangular data (CC169)

December 6, 2021 • PD Schloss • 1 min read • •

The R scan function is key if you need to read in non-rectangular and any irregular shaped data. In this episode, Pat demonstrates scan’s arguments to read in a lower triangular phylip-formatted distance matrix. This is part of a series of videos demonstrating how to functions from base R to make these data compatible with tools from the tidyverse

A file with the simple distance matrix can be obtained here. The data were generated in our Kozich et al. 2013 paper using samples from the Schloss et al. 2012 paper.
