DATA FRAME | Read counts |
dataMetrics |
LIST | Differential expression metrics. This object must contain one column named "logFC" and one column named "PValue". |
dataSE |
SUMMARIZEDEXPERIMENT | Summarized experiment format that can be used in lieu of data; default NULL |
option |
CHARACTER STRING ["hexagon" | "allPoints"] | The background of plot; default "hexagon" |
pointColor |
CHARACTER STRING | Color of overlaid points on scatterplot matrix; default "orange" |
A Shiny application that shows a volcano plot and allows users to overlay genes depending on two values, usually a statistical value (such as P-value) and a magnitude change value (such as log fold change). The user can download a file that contains the gene IDs that pass these thresholds.
# The first pair of examples use data and dataMetrics objects as input.
# The last pair of examples create the same plots now using the
# SummarizedExperiment (i.e. dataSE) object input.
# Example 1: Create interactive volcano plot of logged data using hexagon
# bins for the background.
