Figure 4From: micropan: an R-package for microbial pan-genomics PCA on a pan-matrix. Each square marks a genome in the two first principal components (directions) of the pan-matrix space. The colors indicate the type of environment from which the genome has been sampled. Note that the magenta genomes are isolated from humans, but without specifying blood, gut or urine. The percentages in the axis labels show how much of the total pan-matrix variation is seen along each principal component.Back to article page
