mtext(text, side = 3, line = 0, outer = FALSE, at = NA, adj = NA, padj = NA, cex = NA, col = NA, font = NA, ...)
side:
on which side of the plot (1=bottom, 2=left, 3=top, 4=right)
line:
on which Margin line, starting at 0 counting outwards
outer:
use outer margins if available
at:
give location of each string in user coordinates. If the component of at corresponding to a particular text item is not a finite value (the default), the location will be determined by adj
adj:
adjustment for each string in reading direction. For strings parallel to the axes, adj = 0 means left or bottom alignment, and adj = 1 means right or top alignment
If adj is not a finite value (the default), the value of par("las") determines the adjustment. For strings plotted parallel to the axis the default is to centre the string
padj:
adjustment for each string perpendicular to the reading direction (which is controlled by adj). For strings parallel to the axes, padj = 0 means right or top alignment, and padj = 1 means left or bottom alignment
If padj is not a finite value (the default), the value of par("las") determines the adjustment. For strings plotted perpendicular to the axis the default is to centre the string
