The script has not been updated to match changes in the spgrass6 package. 
west and south in line 117 of the script need to be changed to w and s 
from spgrass6 >= 0.3. The list in line 118 will need changing to 
data.frame for sp >= 0.9 and R >= 2.4.0. The script would be more robust 
if is used the mechanisms described in the GRASS book for argument 
passing. It could also condition on package releases.

Apart from that, the script depends on using xpdf to view pdf files, an 
you don not have it installed or on your path.
