plot.geodata | R Documentation |
This function produces a 2 x 2 display with the following plots: the first indicates the spatial locations assign different colors to data in different quartiles, the next two shows data against the X and Y coordinates and the last is an histogram of the data values or optionally, a 3-D plot with spatial locations and associated data values.
## S3 method for class 'geodata' plot(x, coords=x$coords, data = x$data, borders, trend="cte", lambda = 1, col.data = 1, weights.divide = "units.m", lowess = FALSE, scatter3d = FALSE, density = TRUE, rug = TRUE, qt.col, ...)
x |
a list containing elements |
coords |
an n x 2 matrix containing in each row Euclidean
coordinates of the n data locations. By default it takes the
element |
data |
a vector with data values. By default it takes the
element |
borders |
If an nx2 matrix or data-frame with the borders of the area is provided, the borders are included in the first plot. By default it searches for a element named "borders" in the geodata object. |
trend |
specifies the mean part of the model. The options are:
|
lambda |
value of the Box-Cox transformation parameter. Two particular cases are lambda = 1 which corresponds to no transformation and lambda = 0 corresponding to the log-transformation. |
col.data |
indicates the column number for the data
to be plotted. Only valid if more than one data-set is available
i.e., if the argument |
weights.divide |
if a vector of weights with the same length as
the data is provided each data is
divided by the corresponding element in this vector.
Defaults divides the data by the element |
lowess |
logical. Indicates whether the function
|
scatter3d |
logical. If |
density |
logical. If |
rug |
logical. If |
qt.col |
colors for the quartiles in the first plot. If missing defaults to blue, green, yellow and red. |
... |
further arguments to be passed to the function
|
A plot is produced on the graphics device. No values are returned.
