[R] create a gui with a button to change graphic?

[Gael de Lannoy]

Hello everybody,

I am wondering if it is possible to create a gui to plot a time series 
that is very big, it's an EEG signal of 20mins. What I would like to do 
is plot the first 5mins, then have a button on the gui that plots the 
next 5mins when pushed.

Is it possible?

Thanks in advance !

Gael.
