plot.xvalid {geoR} | R Documentation |
This function produces ten plots with the results produced by the
cross-validation function xvalid
.
plot(x, coords, borders = NULL, ask = TRUE, error = TRUE, std.error = TRUE, data.predicted = TRUE, pp = TRUE, map = TRUE, histogram = TRUE, error.predicted = TRUE, error.data = TRUE, ...)
x |
an object of the class "xvalid" , typically an output
from the function xvalid . |
coords |
an n x 2 object containing coordinates of the (cross-)validation locations. |
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. |
error |
logical. Defines whether the plots for the errors (error = data - predicted) will be produced. |
std.error |
logical. Defines whether the plots for the standardised errors will be produced. |
data.predicted |
logical defining whether a plot of data versus
predicted should be displayed. Defaults to TRUE . |
pp |
logical defining whether a pp plot
should be displayed. Defaults to TRUE . |
map |
logical defining whether a map of the errors
should be displayed. Defaults to TRUE . |
histogram |
logical defining whether a histogram of the errors
should be displayed. Defaults to TRUE . |
error.predicted |
logical defining whether a plot of errors versus
predicted should be displayed. Defaults to TRUE . |
error.data |
logical defining whether a plot of errors versus
data should be displayed. Defaults to TRUE . |
... |
other arguments to be passed to the function
plot . |
No value returned. Plots are produced on the current graphics device.
xvalid
for the cross-validation computations.
