axisIntervals | R Documentation |
Adds an axis (axisintervals) or two axes (axesIntervals) to the current plot with tick marks delimiting interval described by labels
axisIntervals(side=1, atTick1=fda::monthBegin.5, atTick2=fda::monthEnd.5,
atLabels=fda::monthMid, labels=month.abb, cex.axis=0.9, ...)
axesIntervals(side=1:2, atTick1=fda::monthBegin.5, atTick2=fda::monthEnd.5,
atLabels=fda::monthMid, labels=month.abb, cex.axis=0.9, las=1, ...)
side |
an integer specifying which side of the plot the axis is to be drawn on. The axis is placed as follows: 1=below, 2=left, 3=above and 4=right. |
atTick1 |
the points at which tick-marks marking the starting points of the intervals are to be drawn. This defaults to 'monthBegin.5' to mark monthly periods for an annual cycle. These are constructed by calling axis(side, at=atTick1, labels=FALSE, ...). For more detail on this, see 'axis'. |
atTick2 |
the points at which tick-marks marking the ends of the intervals are to be drawn. This defaults to 'monthEnd.5' to mark monthly periods for an annual cycle. These are constructed by calling axis(side, at=atTick2, labels=FALSE, ...). Use atTick2=NA to rely only on atTick1. For more detail on this, see 'axis'. |
atLabels |
the points at which 'labels' should be typed. These are constructed by calling axis(side, at=atLabels, tick=FALSE, ...). For more detail on this, see 'axis'. |
labels |
Labels to be typed at locations 'atLabels'. This is accomplished by calling axis(side, at=atLabels, labels=labels, tick=FALSE, ...). For more detail on this, see 'axis'. |
cex.axis |
Character expansion (magnification) used for axis annotations ('labels' in this function call) relative to the current setting of 'cex'. For more detail, see 'par'. |
las |
line axis style; see |
... |
additional arguments passed to |
The value from the third (labels) call to 'axis'. This function is usually invoked for its side effect, which is to add an axis to an already existing plot.
axesIntervals
calls axisIntervals(side[1], ...)
then
axis(side[2], ...)
.
An axis is added to the current plot.
