You could use bquote. Something like this:
a<-c(1,2,3,4)
b<-c(1,2,3,4)
nTrials <- length(a)
for (trial in 1:nTrials) {
plot(x=a[1:trial], y=b[1:trial],
ylab=expression(paste("Apple"["P"])),
xlab=expression(paste("Banana"^"th")),
main=bquote(italic("i-")~.(trial)^"th"~"choice"))
}

Subject: [R] Loop for main title in a plot
Hi all,
I have a problem in including my plot in a loop. Here is a simple example for
one plot:
# Plot simple graph with super- and subscript
a<-c(1,2,3,4)
b<-c(1,2,3,4)
plot(x=a,y=b,
ylab=expression(paste("Apple"["P"])),
xlab=expression(paste("Banana"^"th")),
main=expression(paste(italic("i-")~"4"^"th"~"choice")))
Now I would like to include the titel (main) as a function of the number of
trails for (trial in 1:nTrials) { plot(
main=expression(paste(italic("i-")~"trial"^"th"~"choice")))
}
e.g. nTrials = 5
The title should look like this:
5th plot: i ^th choice
4th plot: i-1 ^th choice
3th plot: i-2 ^th choice and so on
I have problems to create that, could you please help me?
Thank you!!
