Answer 1

see this thread, it deals specifically with the problem here

and gives a solution that appears to work.

You can add this to your plot

+ opts(panel.grid.minor = theme_blank()) 
+ opts(panel.grid.major = theme_blank()) 
+ opts(axis.line = theme_segment())

Since version 0.9.2, opts has been replaced by theme:

+ theme(panel.grid.minor = element_blank()) 
+ theme(panel.grid.major = element_blank()) 
+ theme(axis.line = element_segment())
