October 3, 2022 • PD Schloss • 1 min read • •

Pat compares and contrasts six approaches to rounding numbers in R using the round, floor, ceiling, trunc, signif, and as.integer functions. Then he applies this type of information to a dataset he is analyzing. Along the way he reviews how to use read_fwf to read in a fixed-width formatted text file. The overall goal of this project is to highlight reproducible research practices using a number of tools. The specific output from this project will be a map-based visual that shows the level of drought across the globe.
