Hi R Graphics Gurus

I am unable to figure out this issues with unevaluated expressions. I'm trying to create a graphic where I calculate the residual from a regression and want to mark each residual with its observation number. So something like

plot(0,0, type = "n", xlim = c(0,10))
for(i in 1:10){
   text(i, 0, substitute(paste(epsilon[i])))
   
}

except that i end up pasting \epsilon_i 10 times and not \epsilon_1, ..., \epsilon_10. i'd be much obliged if anyone can put me out of my misery and let me know how i am goofing up.

many thanks
