To get started using the toolkit you will need to do the following. All of
which are described in more detail below.
It is not necessary to know how to write code in R in
order to use this toolkit. Some basic knowledge given here should
be adequate.
The Extremes Toolkit depends on two packages: tcltk
and ismev. The package, tcltk, is already installed with
R, but the software Tcl/Tk must be on your system and R must know where
it is located. To check if this is set up, from the R prompt try
> library( tcltk)
> demo( tkdensity)
If this works, then you will not need to type these commands in the future.
Step 1a: Install the toolkit, extRemes, onto your system.
