Re: [R] Regions of significance plots with ggplot2

2012-06-05 Thread Paul Murrell

Hi

Here's one way to approach it ...

ggplot(data.frame(x=1:10, y=1:10)) +
  geom_polygon(aes(x=xx, y=yy), fill=grey70,
   data=data.frame(xx=c(0, 0, 4, 4), yy=c(0, 11, 11, 0))) +
  geom_point(aes(x=x, y=y))

... (supply a separate data source for the background region polygon).

I am new to ggplot2 and can't see any obvious way to create distinct
coloured regions for the background, nor can I find any relevant examples.



Any guidance appreciated.

regions of significance, if this is of interest to anyone:

 ... (supply a separate data source for the background region polygon).

and note that you can use +/- Inf for convenience,

ggplot(data.frame(x=1:10, y=1:10)) +
  annotate(polygon, x=c(-Inf, -Inf, 4, 4), y=c(-Inf, Inf, Inf, -Inf),
  fill=grey70, alpha =0.5) +
 geom_point(aes(x=x, y=y))
