findScranMarkers | R Documentation |
Identify marker genes for all or selected clusters based on scran's implementation of findMarkers.

expression_values = c("normalized", "scaled", "custom"),

group_1 = NULL,
group_2 = NULL,
verbose = FALSE,

giotto object |
expression_values |
gene expression values to use |
cluster_column |
clusters to use |
subset_clusters |
selection of clusters to compare |
group_1 |
group 1 cluster IDs from cluster_column for pairwise comparison |
group_2 |
group 2 cluster IDs from cluster_column for pairwise comparison |
verbose |
be verbose (default = FALSE) |

additional parameters for the findMarkers function in scran |
This is a minimal convenience wrapper around
the findMarkers
function from the scran package.
To perform differential expression between cluster groups you need to specificy cluster IDs to the parameters group_1 and group_2.
