[R] Error unary operator

[John Kane]

it looks like 
 facet_grid(Aeventexhumed ~ Rayos)
 + geom_smooth(method="lm", fill=NA) + ylim(c(0, 7))

should read 

 facet_grid(Aeventexhumed ~ Rayos) + 
        geom_smooth(method="lm", fill=NA) + ylim(c(0, 7))

In ggplot the + must be on the preceding line.
