Solution probably here, but complicated... https://rpubs.com/will_townes/sparse-apply

referenced here: https://stackoverflow.com/questions/29901199/apply-for-sparsematrix-in-r

Instead, I use:

if (!requireNamespace("BiocManager", quietly = TRUE))
  install.packages("BiocManager")

BiocManager::install("sparseMatrixStats")

sparseMatrixStats::rowQuantiles()
irequire(sparseMatrixStats)

expr.q90 = iround(sparseMatrixStats::rowQuantiles(x, probs = quantileX) )

The calculation seem to be solved, but Calcq90Expression() >>> qhistogram() >>> qqSave() just cant save the output.

### Keeps hanging
>     qhistogram(log2.gene.expr.of.the.90th.quantile)

# output just before qqSave

### Saving works in 
xxx = qplot(1:11); ggsave(plot = xxx, filename = "xxx.png")
xxx = qplot(1:11); cowplot::save_plot(plot = xxx, filename = "xxxCOW.png") # used

Problem is qHist and vector names: "Vector too many names. Messed up auto-coloring + label.
