Add text box
Add text to plot, justified, in a box
textbox(x, y, textlist, justify=c('l','c','r'), cex=1, leading=0.5, box=TRUE,
adj=c(0,0), font=NULL, vfont=NULL, col=NULL, border=NULL, fill=NA, density=NULL,
angle=45, lty=par("lty"), lwd=par("lwd"), margin=0)x |
x position: a vector with min. and max. x-position |
y |
y position: location of the top of the box |
textlist |
a vector of text strings |
justify |
x alignment: 'l'=left, 'c'=center, 'r'=right. |
cex |
character expansion |
leading |
inter-line spacing |
box |
whether to draw a box around the text |
adj |
adjustment for x and y position, default is no adjustment, see Details |
font |
text font, see Details |
vfont |
text font, see Details |
col |
text color |
border |
box border color |
fill |
box fill color |
density |
box shading line density, see Details |
angle |
box shading line angle, see Details |
lty |
box border and shading line types, see Details |
lwd |
box border and shading line width, see Details |
margin |
amount to adjust box border in or out. See Details |
Draws text in the box by pasting the textlist vector together, splitting it into words, and then adding words to the current line until the line is wide enough before moving on to the next line.
margin may be a vector of 1, 2, or 4 values, corresponding to adjustment of all borders (1 value), top/bottom and left/right borders (2 values), or bottom/left/top/right borders (4 values). A positive value moves text inwards from specified (x,y) position with border remaining at (x,y), and a negative value moves the border outwards from (x,y) with the text remaining at (x,y).
The density and angle arguments have the same behavior as in the rect function. The adj, font and vfont arguments have the same behavior as in the text function. The lty and lwd arguments have the same behavior as in the lines function.
y-position of bottom line of box, or y-position of next line if there is no box.
