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.

...y.
I implemented your solution to my problem but ...
For some of my column there is not enough data to do t-test so it gives me
error and stops the for loop, is any graceful way to check for error msg and
say ok if there is no $p.value continue to the next column
Once again thx for help.
