I think what Bert was hoping you would do was read the plotmath page and figure
it out on your own but that can be a bit tricky when working with expression
object vectors. Here is (perhaps) a step forward:
vectorA = c( bquote("TNF-"*alpha), bquote("IFN-"*gamma) )
for(ii in vectorA) {
plot(0:1,0:1)
title(main = ii)
}
Now as Jim Holtman is fond of saying... what problem were you (really) trying
to solve?
