textflag(mid, radx, rady, rx = rady, dr = 0.01, 
         col = femmecol(100), lcol = "white", 
         bcol = lcol, lwd = 2, angle = 0, lab = NULL, 
         leftright = TRUE, tcol = NULL, ...)

Arguments

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; the box will be filled from left to right.

lcol

line color surrounding box.

bcol

line color to remove the ellipse from the rectangular box.

tcol

text color.

lwd

line width of line surrounding the box.

angle

rotation angle, degrees.

lab

one label or a vector string of labels to be added in box.

leftright

if TRUE then coloring is from left to right else the coloring is from bottom to top box (for angle = 0).

...

other arguments passed to function text.

Details

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.

This function is similar to function roundrect, except that coloring is from left to right.
