Par args xaxs and yaxs option d
Implements par('xaxs') and par('yaxs') option 'd'.
xaxsd(usr = par()$usr[1:2]) yaxsd(usr = par()$usr[3:4])
usr |
a length-2 vector defining the length of the x-axis or y-axis. |
Implements par('xaxs') and par('yaxs') option 'd', i.e. uses previous axis scales in a new plot.
By default returns xlim/ylim args to match current setting of
par()$usr, i.e. previous plot scales. Specifying usr gives scales
with the usr args at the extremes. If par('xlog') or par('ylog') are set the
returned limits are antilogged (to base 10).
