plotCodes {CATALYST} | R Documentation

## tSNE and PCA on SOM codes

### Description

Plots the tSNE and PCA representing the SOM codes as inferred by FlowSOM. Sizes are scaled to the total number of events assigned to each cluster, and points are color according to their cluster ID upon ConsensusClusterPlus metaclustering into `k` clusters.

### Usage

    plotCodes(x, k = "meta20", k_pal = CATALYST:::.cluster_cols)

### Arguments

`x` | a `SingleCellExperiment`.
`k` | character string. Specifies the clustering to use for color coding.
`k_pal` | character string specifying the cluster color palette; If less than `nlevels(cluster_ids(x, k))` are supplied, colors will be interpolated via `colorRampPalette`.

### Value

a `ggplot` object.

### Examples

    # construct SCE & run clustering
    data(PBMC_fs, PBMC_panel, PBMC_md)
    sce <- prepData(PBMC_fs, PBMC_panel, PBMC_md)
    sce <- cluster(sce)

    plotCodes(sce, k = "meta14")

    # use custom cluster color palette
    plotCodes(sce, k = "meta12",
      k_pal = c("lightgrey", "cornflowerblue", "navy"))
