Re: [R] Highliting a text in a plot
How about this:
hilight - function(x,y,s, bg=yellow) {
text.width - strwidth(s)
text.height - strheight(s)
rect(x,y,x+text.width,y+text.height,col=bg,border=NA)
text(x,y,s,adj=c(0,0))
}
plot(1:10,1:10,type=b)
hilight(4,4,Point)

Hi everyone,
I want to highlight something in a plot.
So I want to write a text with a yellow background.
I tried to make use of text(x,y,hallo,bg=yellow)
but that does not work.
I know I am a handful. Sorry!
Maja!

Re: [R] Highliting a text in a plot
Maja: This will work. It's quick. It's easy. And it probably isn't what you want because there is room for an unplotted symbol on the left. But it might suffice. plot(NA, xlim=0:1, ylim=0:1)## legend(x=0.5, y = 0.5, hallo, bg=yellow, col=dark blue, box.lty=0) You can look at the code for legend (?legend) and modify it, or use parts of it for your own function.
