[Bug-datamash] cumulative sum in datamash?

[Matthew Mark Parks]

Hello,

I've been looking for an easy command line tool like datamash for years. writing R code or complicated awk scripts for scratch work is unduly laborious.

I noticed that  a cumulative sum function is missing from datamash. An immediate extension would be a cumulative distribution function  (cumulative sum divided by total counts)  This is often extremely helpful in basic  statistical exploration.

Thank you,

Matthew
