A.6  Why do R lattice graphics not work?

The commands in package lattice have different behavior than the
standard plot commands in the base package: lattice commands return an
object of class "trellis", the actual plotting is performed by the
print method for the class. Encapsulating calls to lattice functions
in print() statements should do the trick, e.g.:

<<fig=TRUE>>=  
library(lattice)  
print(bwplot(1:10))  
@

should work.
