plotSCEBarColData {singleCellTK} | R Documentation

## Bar plot of colData.

### Description

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

### Usage

    plotSCEBarColData(
      inSCE,
      sample = NULL,
      coldata,
      groupBy = NULL,
      dots = TRUE,
      xlab = NULL,
      ylab = NULL,
      axisSize = 10,
      axisLabelSize = 10,
      dotSize = 1,
      transparency = 1,
      defaultTheme = TRUE,
      gridLine = FALSE,
      summary = NULL,
      title = NULL,
      titleSize = NULL,
      combinePlot = TRUE
    )

### Arguments

`inSCE` | Input SingleCellExperiment object with saved dimension reduction components or a variable with saved results. Required.
`sample` | Character vector. Indicates which sample each cell belongs to.
`coldata` | colData value that will be plotted.
`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.
`dots` | Boolean. If TRUE, will plot dots for each violin plot. Default TRUE.
`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.
`dotSize` | Size of dots. Default 1.
`transparency` | Transparency of the dots, values will be 0-1. Default 1.
`defaultTheme` | Removes grid in plot and sets axis title size to 10 when TRUE. Default TRUE.
`gridLine` | Adds a horizontal grid line if TRUE. Will still be drawn even if defaultTheme is TRUE. Default FALSE.
`summary` | Adds a summary statistic, as well as a crossbar to the violin plot. Options are "mean" or "median". Default NULL.
`title` | Title of plot. Default NULL.
`titleSize` | Size of title of plot. Default 15.
`combinePlot` | Boolean. If multiple plots are generated (multiple samples, etc.), will combined plots using 'cowplot::plot_grid'. Default TRUE.

### Value

a ggplot of the barplot of coldata.

### Examples

    plotSCEBarColData(
      inSCE = mouseBrainSubsetSCE,
      coldata = "age", groupBy = "sex"
    )
