Prime or dash in plotmath().
It looks like these four examples give all the same thing. You may pick
the one that suits best in your case.
par(mfrow=c(2,2))
plot(1,1,xlab=expression(paste(K,"'",(t),sep="")))
plot(1,1,xlab=expression(paste(K,"'",(t))))
plot(1,1,xlab=expression(paste("K'(t)")))
plot(1,1,xlab=expression("K'(t)"))

I've had to struggle a bit to get the prime/dash derivative notation into a plotmath expression. The use of expression(K'(t)) gives me a syntax error. The best I've been able to come up with is expression(paste(K,"'",(t),sep="")) Is this the ``accepted'' procedure, or is there a more direct route? cheers, Rolf Turner rolf at math.unb.ca
