mtext {base} | R Documentation |
text
is written in one of the four margins (side
) of the plot.
line
measures the distance outwardly in character size units.
mtext(text, side = 3, line = 0, outer = FALSE, at = NULL, adj = NA, ...)
text |
character string to be written. |
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 in user-coordinates. If length(at)==0
(default), the location will correspond to par("adj") . |
adj |
length = 1 or 2 : adjustment in x- (and optionally y-)
direction. If adj isn't finite (default), a default is setup,
using par("las") (and not par("adj") ! |

Further graphical parameters; currently supported are: |
cex |
character expansion factor (default = 1). |
col |
