cluster_export: Export a column with cluster results

In LieberInstitute/spatialLIBD: spatialLIBD: an R/Bioconductor package to visualize spatially-resolved transcriptomics data

Export a column with cluster results

Description

This function creates a clusters.csv file similar to the ones created by SpaceRanger at outs/analysis/clustering but with the key column that combines the barcode and the sample_id, which is needed when the spe object contains data from multiple samples given that the barcodes are duplicated.

Usage

cluster_export(
  spe,
  cluster_var,
  cluster_dir = file.path(tempdir(), "exported_clusters"),
  overwrite = TRUE
)

Arguments

spe	Defaults to the output of fetch_data(type = 'spe'). This is a SpatialExperiment-class object with the spot-level Visium data and information required for visualizing the histology. See fetch_data() for more details.
cluster_var	A character(1) with the name of the variable you wish to export.
cluster_dir	A character(1) specifying the output directory, similar to the outs/analysis/clustering produced by SpaceRanger.
overwrite	A logical(1) indicating whether to overwrite the spe$key.

Value

The path to the exported clusters.csv file.

Examples

if (enough_ram()) {
    ## Obtain the necessary data
    if (!exists("spe")) spe <- fetch_data("spe")

    ## Export two cluster variables
    cluster_export(spe, "spatialLIBD")
    cluster_export(spe, "GraphBased")
}
