ggtess3Q | R Documentation |
This function displays geographic maps of ancestry coefficients using the ggplot syntax.
ggtess3Q(Q, coord, resolution = c(300, 300), window = NULL,
background = TRUE, map.polygon = NULL, raster.filename = NULL,
interpolation.model = FieldsKrigModel(10), col.palette = CreatePalette())
Q |
an object of class |
coord |
a numeric matrix of dimension |
resolution |
an integer vector |
window |
an integer vector for the plotting window, such that |
background |
if |
map.polygon |
an object of class |
raster.filename |
a raster file name used to compute the background stencil.
This is an alternative method to crop interpolating surfaces. The default method uses |
interpolation.model |
an interpolation model used to compute the interpolating surface. Interpolation models can use the
functions |
col.palette |
a list of color palettes. Color palettes can be defined by using the function |
None
