A geom that draws nothing. It just creates an empty layer.
geom_blank()
has no parameters.
Note that while geom_blank()
draws nothing, ggplot2 needs a way to compute the x and y scales of the plot. Thus, we have to provide a data frame and an x and a y aesthetic somewhere. This could be as arguments to geom_blank()
, but here we pass the information as arguments to ggplot(...)
itself.
d=data.frame(x=c(1,2,3,4), y=c(4,5,6,7)) ggplot(data=d, mapping=aes(x=x, y=y)) + geom_blank() + opts(title="geom_blank", plot.title=theme_text(size=40, vjust=1.5))
