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.
The question is if it is not better to do the whole plot again and just
add the one text in the end. At least if you want to plot into non
screen device: You end up with ll those layers of text in the output
that makes it larger and additionally slows down the rendering of the
whole plot.

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
}
