textflag: adds a filled rounded rectangular box with a text to a plot

Description

adds a rectangular box with rounded left and right edges to a plot

Usage

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.

Examples

Run this code

emptyplot()
textflag(mid = c(0.5, 0.5), radx = 0.5, rady = 0.1, 
         lcol = "white",  lab = "hello", cex = 5, font = 2:3)
 
textflag(mid = c(0.5, 0.15), radx = 0.5, rady = 0.1, 
         rx = 0.3,lcol = "black", lab = "hello 2", cex = 4, 
         font = 2, angle = 20, tcol = "darkblue")
  
textflag(mid = c(0.5, 0.85), radx = 0.5, rady = 0.1, rx = 0.03,
         lcol = "white", lab = "hello 3", cex = 4, font = 2, 
         leftright = FALSE)
