compareSCEs {splatter} | R Documentation

## Compare SingleCellExperiment objects

### Description

Combine the data from several SingleCellExperiment objects and produce some basic plots comparing them.

### Usage

    compareSCEs(
      sces,
      point.size = 0.1,
      point.alpha = 0.1,
      fits = TRUE,
      colours = NULL
    )

### Arguments

`sces` | named list of SingleCellExperiment objects to combine and compare.
`point.size` | size of points in scatter plots.
`point.alpha` | opacity of points in scatter plots.
`fits` | whether to include fits in scatter plots.
`colours` | vector of colours to use for each dataset.

### Details

The returned list has three items:

`RowData`

  Combined row data from the provided SingleCellExperiments.

`ColData`

  Combined column data from the provided SingleCellExperiments.

`Plots`

  Comparison plots

  `Means`

    Boxplot of mean distribution.

  `Variances`

    Boxplot of variance distribution.

  `MeanVar`

    Scatter plot with fitted lines showing the mean-variance relationship.

  `LibrarySizes`

    Boxplot of the library size distribution.

  `ZerosGene`

    Boxplot of the percentage of each gene that is zero.

  `ZerosCell`

    Boxplot of the percentage of each cell that is zero.

  `MeanZeros`

    Scatter plot with fitted lines showing the mean-zeros relationship.

  `VarGeneCor`

    Heatmap of correlation of the 100 most variable genes.

The plots returned by this function are created using `ggplot` and are only a sample of the kind of plots you might like to consider. The data used to create these plots is also returned and should be in the correct format to allow you to create further plots using `ggplot`.

### Value

List containing the combined datasets and plots.

### Examples

    sim1 <- splatSimulate(nGenes = 1000, batchCells = 20)
    sim2 <- simpleSimulate(nGenes = 1000, nCells = 20)
    comparison <- compareSCEs(list(Splat = sim1, Simple = sim2))
    names(comparison)
    names(comparison$Plots)
