modeReducedDim {iSEEu} | R Documentation

## App pre-configured to compare multiple reduced dimension plots

### Description

This mode launches a Shiny App preconfigured with multiple linked reduced dimension plots for interactive data exploration of the `SingleCellExperiment` object.

### Usage

    modeReducedDim(
      se,
      includeNames = reducedDimNames(se),
      colorBy = NULL,
      ...,
      plotWidth = NULL
    )

### Arguments

`se` | An object that coercible to SingleCellExperiment
`includeNames` | Character vector with the names of reduced dimensions to display as individual panels. The default uses all available in `reducedDimNames(se)`.
`colorBy` | Character scalar controlling coloring of cells. Must match either to one of `colnames(colData(se))` or `rownames(se)`. If coloring by a colData column, a column data plot is opened in addition to the reduced dimension panels. If coloring by a feature, a row statistics table is openend in addition to the reduced dimension panels, from which the latter are receiving the color.
`...` | Additional arguments passed to `iSEE`.
`plotWidth` | The grid width of linked plots (numeric vector of length either 1 or equal to `length(includeNames)`). The total width of the window is 12, so `plotWidth = 4` for example will show three panels per row. If `plotWidth = NULL` (the default), a value will be estimated depending on the number of reduced dimension panels.

### Value

A Shiny app object is returned.

### Examples

    library(scRNAseq)

    # Example data ----
    sce <- ReprocessedAllenData(assays="tophat_counts")
    class(sce)

    library(scater)
    sce <- logNormCounts(sce, exprs_values="tophat_counts")
    sce <- runPCA(sce, ncomponents = 30)
    sce <- runTSNE(sce)
    sce <- runUMAP(sce)
    reducedDimNames(sce)

    # launch the app ----
    # ... coloring by a column data variable
    app <- modeReducedDim(sce, colorBy = "Primary.Type")
    if (interactive()) {
        shiny::runApp(app, port=1234)
    }
    # ... coloring by a feature
    app <- modeReducedDim(sce, colorBy = "Scnn1a")
    if (interactive()) {
        shiny::runApp(app, port=1234)
    }
