I'm working on single-cell RNA seq data with the Seurat package. I want to check the expression of some genes in some of the cell types with a heat map. currently, this code shows all of the cell types :
`dittoHeatmap(Seurat.integrated, genes, annot.by = c("PatientID", "CellType"))`
how can I show the expression of genes just in some of my cell types in heatmap?
Any recommendations or solutions would be appreciated.
