Do not use T as a name for object as it can be confused with logical T/F
par(fig=....) is what you want.

> ## PLOT 1
> plot(T,  30*exp(-0.65*T),

> points(T, 30*exp(-0.15 * T), type = "l", lty = "39")
> ## PLOT 2

par(new=TRUE)
par(fig=c(.3,.95,.4,.95))

> plot(T,  30*exp(-0.65*T),
>      type = "l",
>      log= "y"
