Calculate average of gene expression per cell type.

get_exprs_avg Calculate average of gene expression per cell type. If condition_oi is provided, only consider cells from that condition.

Usage

get_exprs_avg(
  seurat_obj,
  celltype_colname,
  condition_oi = NULL,
  condition_colname = NULL,
  assay_oi = NULL,
  ...
)

Arguments

seurat_obj: Seurat object
celltype_colname: Name of the meta data column that indicates the cell type of a cell
condition_oi: If provided, subset seurat_obj so average expression is only calculated for cells belonging to condition_oi
condition_colname: Name of the meta data column that indicates from which group/condition a cell comes from
assay_oi: Which assay need to be used for DE calculation. If NULL, will use DefaultAssay
...: Arguments passed to Seurat::AverageExpression, usually for slot/layer to use (default: data)

Value

Data frame with average gene expression per cell type.

Examples

if (FALSE) { # \dontrun{
seurat_obj <- readRDS(url("https://zenodo.org/record/3531889/files/seuratObj.rds"))
seurat_obj$celltype <- make.names(seuratObj$celltype)
# Calculate average expression across conditions
expression_info <- get_exprs_avg(seurat_obj, "celltype")
# Calculate LCMV-specific average expression
expression_info <- get_exprs_avg(seurat_obj, "celltype", condition_oi = "LCMV", condition_colname = "aggregate")
} # }
