Hello,

Does anyone know how to get the rounding method used for the axis tick
numbers/values in plot()?

I'm using mtext() to plot the values used to plot vertical and horizontal
lines (using abline()) and I'd like these vertical and horizontal line
values to be rounded like the axis tick values are rounded.

In other words, I want numbers plotted with mtext() to be rounded in the
same fashion as the axis values given by default by plot().

thank you very much for your help!
