tm_layout controlls title, margins, aspect ratio, colors, frame, legend, among many other things. The function tm_legend is a shortcut to access all legend. arguments without this prefix. The other functions are wrappers for two purposes: the tm_format_ functions specify position related layout settings such as margins, and the tm_style_ functions specify general styling related layout settings such as colors and font. Typically, the former functions are shape dependent, and the latter functions are shape independent. See details for predefined styles and formats. With the global option tmap.style, a default style can be specified. Multiple tm_layout elements (or wrapper functions) can be stacked: called arguments will be overwritten.

Use "#00000000" for transparency.seq for sequential palettes, div for diverging palettes, and cat for categorical palettes. By default, Color Brewer palettes (see (see RColorBrewer::display.brewer.all)) are used. It is also possible provide a vector of colors for any of these items.sepia.intensity=0). All colored used in the map are adjusted with this effect.saturation=0 is greyscale and saturation=1 is normal. A number larger than 1 results in very saturated maps. All colored used in the map are adjusted with this effect. Hacking tip: use a negative number.NA, it is determined by the bounding box (see argument bbox of tm_shape), the outer.margins, and the inner.margins. If 0, then the aspect ratio is adjusted to the aspect ratio of the device.between.margin)"arrow", "4star", "8star", "radar", "rose". Of course, only applicable if a compass is shown. The compass type can also be set within tm_compass.extent object. By default, the boundaries are c(-180, 180, -90, 90). Useful for rojected world maps. Often, it is useful to crop both poles (e.g., with c(-180, 180, -88, 88))."WGS84", other frequently used datums are "NAD83" and "NAD27". Any other PROJ.4 character string can be used.free.scales=FALSE).legend.outside=TRUE. One of: "right", "left", "top", or "bottom".legend.outside=TRUE. If the first value of legend.outside.position is "top" or "bottom", then it is the width of the legend, else it is the height of the legend."left", "LEFT", "center", "right", or "RIGHT" for the first value and "top", "TOP", "center", "bottom", or "BOTTOM" for the second value, or this vector contains two numeric values between 0 and 1 that specifies the x and y coordinates of the left bottom corner of the legend. The uppercase values correspond to the position without margins (so tighter to the frame). By default, it is automatically placed in the corner with most space based on the (first) shape object. If legend.outside=TRUE, this argument specifies the legend position within the outside panel."left" , "right", "center", "bottom", and "top". Numeric values of 0 specify left/bottom alignment and 1 right/top alignment. This option is only used, if legend.position is specified by numeric coordinates.legend.height, the histogram is downscaled as well.legend.width.labels is undefined. Parameters are:
format of the numbers is "g". Otherwise, format="f", and text.separator, text.less.than, and text.or.more are used. Also, the numbers are automatically rounded to millions or billions if applicable."f", i.e. the standard notation xxx.xxx, is used. If scientific=TRUE then "g", which means that numbers are formatted scientically, i.e. n.dddE+nn if needed to save space.format="f", and the number of significant digits otherwise.formatClegend.width.TRUE to match with the overall background color bg.color.legend.bg.color is used (normally 1).legend.hist.bg.color is used (normally 1).legend.outside is TRUElegend.position).TRUE to match with the overall background color bg.color. By default, it is TRUE if legend.frame is TRUE or a color.title.bg.color is used (normally 1).TRUE, the title will be placed in the panel header instead of inside the map. By default, it is TRUE when small multiples are created with the by variable. (See tm_facets)panel.show is TRUE. For cross tables facets, it should be a list containing the row names in the first, and column names in the second item.tm_facets's by is specified with two variables). The second is the rotation angle of the column panels.top or bottom. Only applicable when attr.outside=TRUE.attr.outside=TRUE.tm_credits, tm_scale_bar and tm_compass. Vector of two values, specifing the x and y coordinates. The first value is "left", "LEFT", "center", "right", or "RIGHT", and the second value "top", "TOP", "center", "bottom", or "BOTTOM". The uppercase values correspond to the position without margins (so tighter to the frame). Positions can also be set separately in the map attribute fuctions. If attr.outside=TRUE, this argument specifies the position of the attributes within the outside panel."left" , "right", "center", "bottom", and "top". Numeric values of 0 specify left/bottom alignment and 1 right/top alignment. This option is only used, if legend.position is specified by numeric coordinates.TRUE, inner and outer margins, legend position, aspect ratio are explicitely shown. Also, feedback text in the console is given.tm_view.tm_view.bg.overlaytm_layout
