I'm trying to extract the data matrix computed by Signac r package when running RegionMatrix(). I know I can plot the data with RegionHeatmap(), but I want to plot the data with another package. So, if I created a region matrix like this:
my_object <- RegionMatrix(my_object , key = "my_region_matrix" , regions = StringToGRanges(top_cluster_genes$gene) , upstream = 2500, downstream = 2500)
How do I go about extracting the data stored within the object under the key "my_region_matrix"? I know it's a pretty basic question, but I've been browsing the returned object and can't find any assay/matrix with that key name.
