Arguments

expr_mat: input single cell matrix
metadata: data.frame with tSNE or umap coordinates
genes: gene(s) to color tSNE or umap
cell_col: column name in metadata containing cell ids, defaults to rownames if not supplied
...: additional arguments passed to [clustifyr::plot_dims()]

Value

list of ggplot object, cells projected by dr, colored by gene expression

Examples

genes <- c(
    "RP11-314N13.3",
    "ARF4"
)

plot_gene(
    expr_mat = pbmc_matrix_small,
    metadata = tibble::rownames_to_column(pbmc_meta, "rn"),
    genes = genes,
    cell_col = "rn"
