[R] HOW TO REMOVE MTEXT FROM PLOT, plotting changing populations with titles in loop
is there a way to hide/undraw mtext (or lines etc.) in a loop like
plot(runif(10))
iterCol <- rainbowPalette(10)
for(i in 1:10){
mtext(paste("this is iteration ", i, sep=""))
points(runif(10),col=iterCol[i])
Sys.sleep(1)
## UNDRAW/HIDE the text so that it does not mess up the plot in the next
iteration
}

It's not perfect, but you could use:
mtext(paste("this is iteration ", i, sep=""),
col="white")
to overwrite it, or polygon() to draw a white rectangle over the text each time.
