Visualizes values stored in the colData slot of a SingleCellExperiment object via a density plot.

plotSCEDensityColData(
  inSCE,
  coldata,
  sample = NULL,
  groupBy = NULL,
  xlab = NULL,
  ylab = NULL,
  baseSize = 12,
  axisSize = NULL,
  axisLabelSize = NULL,
  defaultTheme = TRUE,
  title = NULL,
  titleSize = 18,
  cutoff = NULL,
  combinePlot = "none",
  plotLabels = NULL
)

Arguments

inSCE

Input SingleCellExperiment object with saved dimension reduction components or a variable with saved results. Required.

coldata

colData value that will be plotted.

sample

Character vector. Indicates which sample each cell belongs to.

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.

baseSize

The base font size for all text. Default 12. Can be overwritten by titleSize, axisSize, and axisLabelSize, legendSize, legendTitleSize.

axisSize

Size of x/y-axis ticks. Default NULL.

axisLabelSize

Size of x/y-axis labels. Default NULL.

defaultTheme

Removes grid in plot and sets axis title size to 10 when TRUE. Default TRUE.

title

Title of plot. Default NULL.

titleSize

Size of title of plot. Default 15.

cutoff

Numeric value. The plot will be annotated with a vertical line if set. Default NULL.

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.

Value

a ggplot of the density plot of colData.

Examples

data("mouseBrainSubsetSCE")
plotSCEDensityColData(
  inSCE = mouseBrainSubsetSCE,
  coldata = "age", groupBy = "sex"
)
