In R, coordinates cross not at O by default. I mean that there is a tiny space before 0.
When code xaxs="i", yaxs="i", the plot will cross at O. [1]set-r-plots-x-axis-to-show-at-y-0,
[2]The "i" is an abbreviation for internal
So, is there an alternative way like xaxs to let the plot not to cross at O in gnuplot?
