Visualizes values stored in the assay slot of a SingleCellExperiment object via a density plot.
plotSCEDensityAssayData( inSCE, feature, sample = NULL, useAssay = "counts", featureLocation = NULL, featureDisplay = NULL, groupBy = NULL, xlab = NULL, ylab = NULL, axisSize = 10, axisLabelSize = 10, defaultTheme = TRUE, cutoff = NULL, title = NULL, titleSize = 18, combinePlot = "none", plotLabels = NULL )
inSCE | Input SingleCellExperiment object with saved dimension reduction components or a variable with saved results. Required. |
---|---|
feature | Name of feature stored in assay of SingleCellExperiment object. |
sample | Character vector. Indicates which sample each cell belongs to. |
useAssay | Indicate which assay to use. Default "counts". |
featureLocation | Indicates which column name of rowData to query gene. |
featureDisplay | Indicates which column name of rowData to use to display feature for visualization. |
groupBy | Groupings for each numeric value. A user may input a vector equal length to the number of the samples in the SingleCellExperiment object, or can be retrieved from the colData slot. Default NULL. |
xlab | Character vector. Label for x-axis. Default NULL. |
ylab | Character vector. Label for y-axis. Default NULL. |
axisSize | Size of x/y-axis ticks. Default 10. |
axisLabelSize | Size of x/y-axis labels. Default 10. |
defaultTheme | Removes grid in plot and sets axis title size to 10 when TRUE. Default TRUE. |
cutoff | Numeric value. The plot will be annotated with a vertical line if set. Default NULL. |
title | Title of plot. Default NULL. |
titleSize | Size of title of plot. Default 15. |
combinePlot | Must be either "all", "sample", or "none". "all" will combine all plots into a single .ggplot object, while "sample" will output a list of plots separated by sample. Default "none". |
plotLabels | labels to each plot. If set to "default", will use the name of the samples as the labels. If set to "none", no label will be plotted. |
a ggplot of the density plot of assay data.
