Legend positions

[aronnyberg]

Added top-left(-0.2) and top-right(1) options for legend setting, . Ran devtools::document so description updated.

Thanks @aronnyberg!

Changes look good. I've updated the branch to make it up to date with the development branch.

Could you please

• Update the news file
• Add yourself as a contributor in the description file
• Add a few tests in the "theme_af works with non default options" section of tests/testthat/test-chart-output.R

In the following example, the legend title ("class") is cut off

ggplot(mpg, aes(x = class, colour = class)) + geom_bar() +theme_af(legend = "top-left")

Could we also add in a bottom-left and bottom-right legend option? I suppose we could also have a top, middle and bottom option for left and right?

Could also look at the theme legend.title.position?

Just to note, its possible to set positions for top/left/right/bottom legends individually in theme. You can also set the position of the legend title.

ggplot(
  mpg, aes(x = class, colour = class, fill = as.character(class))) +
  geom_bar() +
  guides(
    fill = guide_legend(position = "top"),
    colour = guide_legend(position = "left")
  ) +
  theme(
    legend.justification.left = c(0, 0.1),
    legend.justification.top = c(0.9, 0),
    legend.title.position = "top"
  )
