How to control height of abline
I use matplot to get the density curve and then I use
abline(v=g$V2, col = 3 ) to get the vertical line.
Goal : I want very small lines at the bottom on the x axis , if possible in the arrow forms instead of vertical lines on the whole graph.
Thanks a lot.

Since t.test takes much more time than parsing loop, I
won't hesitate to do a loop on the columns.
