R help - Nov 2012 - how to create dispersion graphic

Hello, somebody can explain how to create dispersion graphic, because i
need to put this dispersion graphics inside a matrix.

The data is the next one:

2 test (mechanics and vector)

open book.

3 test (algebra, analysis y statistics)

closed book.

Also could you explain which is the use of

scor(bootstrap)

And how can be used for create a matrix of graphics?

Thanks,

Tania
