add an "outside" argument to geom_rug() to allow for moving rug tasse…

…ls to outside the plot area

Can I get you to run devtools::document() so the documentation gets updated

[njtierney]

library(ggplot2)

# current behaviour with tassels inside figure area
ggplot(airquality,
       aes(x = Ozone,
           y = Solar.R)) + 
  geom_rug()

# move the tassels outside, remembering to turn off clipping
ggplot(airquality,
       aes(x = Ozone,
           y = Solar.R)) + 
  geom_rug(outside = TRUE) + 
  coord_cartesian(clip = "off")

# move the tassels to top right side, and expand margin
ggplot(airquality,
       aes(x = Ozone,
           y = Solar.R)) + 
  geom_rug(outside = TRUE,
           sides = "tr") + 
  coord_cartesian(clip = "off") +
  theme(plot.margin = margin(1,1,1,1, "cm"))

Here's a reprex to demonstrate the behaviour:

library(ggplot2)

# current behaviour with tassels inside figure area
ggplot(airquality,
       aes(x = Ozone,
           y = Solar.R)) + 
  geom_rug()

# move the tassels outside, remembering to turn off clipping
ggplot(airquality,
       aes(x = Ozone,
           y = Solar.R)) + 
  geom_rug(outside = TRUE) + 
  coord_cartesian(clip = "off")

# move the tassels to top right side, and expand margin
ggplot(airquality,
       aes(x = Ozone,
           y = Solar.R)) + 
  geom_rug(outside = TRUE,
           sides = "tr") + 
  coord_cartesian(clip = "off") +
  theme(plot.margin = margin(1,1,1,1, "cm"))

@njtierney If you're up for another PR I think it would be worth adding a test for this new behavior.

[njtierney]

@karawoo - great idea! I'll get cracking on that now. :)
