National and urban maps with Ulaanbaatar inset panels

Compose ordinary ggplots without shifting any analytical coordinates. All panels share fill limits and breaks. When supplying different data to the national and urban panels, their fill expressions must have compatible units. Insets have independent map scales.

Usage

mn_inset_ub(
  x = NULL,
  ub = NULL,
  fill = NULL,
  label = FALSE,
  title = NULL,
  limits = NULL,
  breaks = NULL,
  ...
)

mn_map_ub(
  x = NULL,
  fill = NULL,
  label = FALSE,
  title = NULL,
  limits = NULL,
  breaks = NULL,
  ...
)

Arguments

x

A national map for mn_inset_ub(), or a UB district/khoroo map for mn_map_ub(). Defaults to aimags or UB districts respectively.

ub

Optional urban data for the inset. By default, select Ulaanbaatar units from x; if none exist, stop rather than invent data.

fill

An unquoted fill column/expression, as in mn_map().

label

Label units in each panel.

title

Overall title.

limits, breaks

Shared fill scale limits and breaks.

...

Additional arguments to mn_map(), such as lang, trans, bins or midpoint.

Value

A patchwork object; requires the optional patchwork package. No input geometry is modified.
