roundrect {shape} | R Documentation |
adds a rectangular box with rounded left and right edges to a plot
roundrect(mid, radx, rady, rx=rady, dr=0.01, col="white", lcol="black", lwd=2, angle=0, ...)
mid |
midpoint (x,y) of the box |
radx |
horizontal radius of the box |
rady |
vertical radius of the box |
rx |
radius of rounded part |
dr |
size of segments, in radians, to draw the rounded line (decrease for smoother) |
col |
fill color of the box |
lcol |
line color surrounding box |
lwd |
line width of line surrounding the box |
angle |
rotation angle, degrees |

arguments passed to function <link>[Shape]filledshape</link> |
radx and rady are the horizontal and vertical radiusses of the box; rx is the horizontal radius of the rounded part.
Here "horizontal" and "vertical" denote the position BEFORE rotation
