[R] editing plot

[Rui Barradas]

Hello,

Maybe


theme(panel.grid.major.x = element_line(size = 0.1, color = "grey"),
         panel.grid.major.y = element_blank(),
         panel.grid.minor = element_blank()
   )



Note that if you remove the y axis grid you must set the x axis grid 
explicitly.

Hope this helps,

Rui Barradas
