Arguments

expr_mat

input single cell matrix

metadata

data.frame with tSNE or umap coordinates

genes

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(
