Heatmaps of top correlated genes

Draws Seurat heatmaps of the most positively and negatively correlated genes from sc_correlation(), using the batlow palette.

Usage

correlation_heatmaps(
  seurat.object,
  correlation.df,
  up.n = 20,
  dn.n = 20,
  goi = "NKG7",
  output.dir = "results/figures/Correlation_analysis/"
)

Arguments

seurat.object

A Seurat object (idents/assay pre-set, ideally downsampled).

correlation.df

Output of sc_correlation().

up.n, dn.n

Number of up / down correlated genes to show.

goi

Gene of interest.

output.dir

Directory to write the PDFs into (created if needed). Use NULL to skip writing.

Value

Invisibly, a list with the up and down heatmap plots.

Examples

if (FALSE) { # \dontrun{
correlation_heatmaps(small_seurat, cor_df, up.n = 20, goi = "NKG7")
} # }
