Arguments

crs: Map crs (see tm_shape()). NA means the crs is specified in tm_shape(). The crs that is used by the transformation functions is defined in tm_shape().
facet.max: Maximum number of facets
facet.flip: Should facets be flipped (in case of facet wrap)? This can also be set via tm_facets_flip()
free.scales: For backward compatibility: if this value is set, it will be used to impute the free arguments in the layer functions
raster.max_cells: Maximum number of raster grid cells. Can be mode specific c(plot = 3000, view = 1000, 1000) (the last value is the fall back default)

value.const: Default visual value constants e.g. the default fill color for tm_shape(World) + tm_polygons(). A list is required with per visual variable a value.
value.na: Default visual values that are used to visualize NA data values. A list is required with per visual variable a value.
value.null: Default visual values that are used to visualize null (out-of-scope) data values. A list is required with per visual variable a value.
value.blank: Default visual values that correspond to blank. For color these are "#00000000" meaning transparent. A list is required with per visual variable a value.
