Scaling an axis with the log scale is straightforward to achieve in R with the scale_x_log10 (or scale_y_log10) and coord_trans functions from ggplot2. In this episode of Code Club, Pat will discuss these two sets of functions and when to use each to help accentuate the differences between gropus that have low abundances. He'll also add a line to indicate the limit of detection using geom_vline/geom_hline.
Pat will use RStudio and the #scale_y_log10, #coord_trans, and scale_x_log10 functions from the #ggplot2, package. The accompanying blog post can be found at https://www.riffomonas.org/code_club/....
