Hi Alexander,
there is a simple solution using bquote
for(i in 1:10){
text(i, 0,bquote(epsilon[.(i)]))
}hth. Alexander Nervedi schrieb:
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_________________________________________________________________[[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
