I am working with single-cell RNA-seq data, using the R package "Seurat" to cluster and visual data-points.
I had two single cell datasets from which I generated two Seurat objects. I then combined the two using MergeSeurat. I did differential gene expression analysis, performed clustering, and ran a tSNE plot.
Now what I want to do is create that same tSNE plot, but color each cell according to the original object from which it came. How do I do this?
