grid.plotarea {RGrace} | R Documentation |
This function draws fully rigged (i.e. with tick marks, tick labels, axis label and - optionally - with grid) left,right,bottom and top axis on the current graphic device.
grid.plotarea(inward=FALSE, grilled=FALSE,gp=gpar(lwd=2,fontsize=12,fontface=1), at=c("","Inf","","Inf"),label=c("X Label","","Y Label", ""), draw=TRUE, vp=NULL, title="")
at |
Character string containing the code used to calculate tick marks
position and tick marks' labels. If at is empty, tick marks
are evenly distributed along axis at position with "pretty numbers"
(see grid.pretty ). Otherwise at are
parsed and evaluated twice in environment with two local variables
RANGE and TICK.LAB set. RANGE contains the current
range of the axis. TICK.LAB is set either to "tick" or
"label". In the former case, if at string is evaluated to
numerical vector, then this values are used as a positions of tick
marks; in the latter case the value may be numerical or character
vector which gives tick marks' labels (tips
of the day: at="Inf" draws an empty axis without ticks and
labels; at="list(tick=0,label=\"Start point\")[[TICK.LAB]]" draws
only one tick at point zero with label "Start point";
at="log10.ticks(RANGE,TICK.LAB)" makes automatic logariphmic axis with
power of 10 labels).
|
label |
Axis title. Can be either character string or expression. If entered
in GUI text box in former case the value must be quoted, in the
latter case it mustn't be quoted but should be wrapped in
expression call.
|
inward |
Direction of tick marks. If TRUE tick marks are drawn inward
plotting area, otherwise - overwise.
|
grilled |
To draw or not to draw grid lines. Grid are always drawn with 1pt wide
dashed gray lines and gp parameter does not have effect on them.
|
gp |
Graphic parameter of axis. Applies to all 4 plotarea's axis with their tick marks , tick labels and axis legends. |
vp,draw |
Standard grob's parameters - viewport to draw onto and does this function actually draw the graphic object or not. |
title |
Character string used for the plotarea identification. Something like a comment string stored with the grob. |
Elements of vector parameters label
and at
corresponds
to bottom,top,left and right axis.
Grob (GRaphic OBject, see grid.grob
) of class "grid.plotarea".
