Adding outliers to a boxplot from precomputed summary statistics

I am working with a large (50 x 800 000) sparse matrix (dgCMatrix) and want to plot a boxplot for the initial inspection of the data. This is a matrix of numeric items, with named rows (genes) and named columns (cells). The best solution I have found is to compute the relevant stats via sparseMatrixStats::rowQuantiles() and feed them directly to a boxplot geom.
