A Shiny app for visual exploration of omic datasets as compositions, and differential abundance analysis using ALDEx2. Useful for exploring RNA-seq, meta-RNA-seq, 16s rRNA gene sequencing and more with visualizations such as principal component analysis biplot (coloured using metadata for visualizing each variable), association plots (igraph), dendrograms and stacked bar plots, and effect plots (ALDEx2). Input is a table of counts and metadata file (if metadata exists), with options to filter data by count or by metadata to remove low counts, or to visualize select samples according to selected metadata. The Shiny app's graphical user interface facilitates visual exploration for new and experienced users of R alike.
