| plot.xvalid {geoR} | R Documentation |
This function produces ten plots with the results produced by the
cross-validation function xvalid.
plot.xvalid(obj, valid.obj, coords = valid.obj$coords,
error.plots = TRUE, std.error.plots = TRUE,
borders = NULL, ask = TRUE)
obj |
an object of the class "xvalid", typically an output
from the function xvalid. |
valid.obj |
a list containing at least the element coords
as described next. Typically an object of the class
"geodata" - a geoR data-set.
The argument coords can be provided instead. |
coords |
an n x 2 matrix containing
coordinates of the (cross-)validation locations in each row.
Defaults to valid.obj$coords, if provided. |
error.plots |
logical. Defines whether the plots for the errors (error = data - predicted) will be produced. |
error.plots |
logical. Defines whether the plots for the standardised errors will be produced. |
borders |
optional. Takes a two column matrix or data-frame with coordinates of the borders. If provided the borders are included in the errors maps. |
ask |
logical. Defines whether or not the user is prompted before each plot is produced. |
No value returned. Plots are produced on the current graphics device.
xvalid for the cross-validation computations.
