Arguments

group_id: id of the component group. Refers to the group_id argument of each component function, such as tm_legend() and tm_title().
position: The position specification of the components in this group: an object created with tm_pos_in() or tm_pos_out(). Or, as a shortcut, a vector of two values, specifying the x and y coordinates. The first is "left", "center" or "right" (or upper case, meaning tighter to the map frame), the second "top", "center" or "bottom". Numeric values are also supported, where 0, 0 means left bottom and 1, 1 right top. See also vignette about positioning.
stack: stacking "horizontal" or "vertical"
frame_combine: put frame around all components that are drawn on the same location. Whether a frame is drawn is still decided by the frame argument of the 'main' (first) component.
equalize: in case frame_combine is FALSE, should the separate frames be equalized, i.e. have the same width (when stacked vertically) or height (when stacked horizontally)?
resize_as_group: in case a component if rescaled because of the limited space, rescale the other components proportionally?
stack_margin: Margin between components
offset: Offset margin between frame and the components block
frame: Should a frame be drawn? By default TRUE for legends, charts and insets, and FALSE otherwise.
frame.color: frame color
frame.alpha: frame alpha transparancy
frame.lwd: frame line width
frame.r: Radius of the rounded frame corners. 0 means no rounding.
bg: Background color the components block. Is usually set in each component function, but if specified here, it will overwrite them.
bg.color: Background color the components block. Is usually set in each component function, but if specified here, it will overwrite them.
bg.alpha: Background alpha transparency of the components block. Is usually set in each component function, but if specified here, it will overwrite them.

Value
