We discuss the use of phyloseq with tools for reproducible research, a practice common in other fields but still rare in the analysis of highly parallel microbiome census data. Seven examples of colored and labeled heatmaps with custom colorscales. Richness estimates were made using the metric for Observed OTUs. Iron (Fe) is a limiting nutrient in large regions of the ocean, but the strategies of prokaryotes to cope with this micronutrient are poorly known. There are multiple example data sets included in phyloseq. 0) packages. frame) that is very friendly for defining a custom ggplot2 graphic. Core heatmaps. The code is working fine but when I try to plot the taxa by class, order, family, genus, or species, the plots are so big that is only shown a part of the legend.
