grid.yaxis | R Documentation |
These functions create and draw a y-axis.
grid.yaxis(at = NULL, label = TRUE, main = TRUE, edits = NULL, name = NULL, gp = gpar(), draw = TRUE, vp = NULL) yaxisGrob(at = NULL, label = TRUE, main = TRUE, edits = NULL, name = NULL, gp = gpar(), vp = NULL)

on the tick marks, or an expression or character vector which

Both functions create a yaxis grob (a graphical object describing a
yaxis), but only grid.yaxis
draws the yaxis (and then only if draw
is TRUE
).
A yaxis grob. grid.yaxis
returns the value invisibly.
If the at
slot of an xaxis grob is not NULL
then
the xaxis will have the following children:
representing the line at the base of the tick marks.
representing the tick marks.
representing the tick labels.
If the at
slot is NULL
then there are no children
and ticks are drawn based on the current viewport scale.
