LinePlotTheme() creates ggplot object with a white background, a relatively large font, and grid lines. EmptyTheme() on the other hand creates a ggplot object with no axes or legends.
Examples
## Not run:X <- data.frame(x=runif(100),y = runif(100), z = runif(100))LinePlotTheme()+ geom_point(data=X,aes(x,y,colour=z))EmptyTheme()+ geom_point(data=X,aes(x,y,colour=z))## End(Not run)
