geom
Draws nothing, but can be a useful way of ensuring common scales between different plots (see expandLimits()). Also, can help to avoid the "No layers in plot" error when building plots using automated tools.
Parameters
The data to be displayed in this layer. If null, the default, the data is inherited from the plot data as specified in the call to letsPlot.
The statistical transformation to use on the data for this layer. Supported transformations: Stat.identity, Stat.bin(), Stat.count(), etc. see Stat.
Position adjustment: positionIdentity, positionStack(), positionDodge(), etc. see Position.
default = true. false - do not show legend for this layer.
default = false. false - do not combine the layer aesthetic mappings with the plot shared mappings.
String or result of the call to the layerKey() function. The key to show in the manual legend. Specifies the text for the legend label or advanced settings using the layerKey() function.
Result of the call to the samplingXxx() function. To prevent any sampling for this layer pass value samplingNone. For more info see sampling.html.
Result of the call to the layerTooltips() function. Specifies appearance, style and content. Set tooltips = tooltipsNone to hide tooltips from the layer.
Specifies the axis that the layer's stat and geom should run along, default = "x". Possible values: "x", "y".
Data-structure containing series of planar shapes and, optionally, associates data series (for example: names of States and their boundaries).
Supported shapes: Point and MultiPoint. All coordinates should be encoded as decimal degrees in WGS84 coordinate reference system.
Can be used with parameter mapJoin for joining data and map coordinates.
Pair of Names or Pair of Lists of Names. Specifies column names to join the data and the map coordinates on.
Pair.first: column name or list of column names in the
datadataframe.Pair.second: column name or list of column names in the
mapdataframe.
By default, all coordinates are converted into degrees of longitude and latitude, and these map coordinates are projected onto the screen coordinates using Mercator projection. Specify useCRS = "provided" to keep the SpatialDataset's original coordinate reference system (CRS).
X-axis value.
Y-axis value.
Transparency level of a layer. Understands numbers between 0 and 1.
Color of the geometry. For more info see: aesthetics.html#color-and-fill.
Color to paint shape's inner points. Is applied only to the points of shapes having inner points. For more info see: aesthetics.html#color-and-fill.
Shape of the point. For more info see: aesthetics.html#point-shapes.
Size of the point.
Width of the shape border. Applied only to the shapes having border.
Rotation angle of the shape, in degrees.
Relates the size of the point to the length of the unit step along one of the axes. Possible values: "x", "y". If not specified, no fitting is performed.
default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the color aesthetic for the geometry.
default = "fill" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the fill aesthetic for the geometry.
Set of aesthetic mappings. Aesthetic mappings describe the way that variables in the data are mapped to plot "aesthetics".
