Plot label axis with expression

Hello,

Use 'parse' for converting from character to expression:

x <- c(100, 50, 10, 1, 0.1, 0.05, 0.001)
plot(log(x), yaxt = "n")

parse(text = sprintf("e^%d", axTicks(2)))
## expression(e^-6, e^-4, e^-2, e^0, e^2, e^4)

axis(2, at = axTicks(2), labels = parse(text = sprintf("e^%d", axTicks(2))), las = 1)
