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.
Details
The number of plots to be produced will depend on the input options.
If the graphics device is set to just one plot (something equivalent
to par(mfcol=c(1,1))) after each graphic being displayed the user will be prompt
to press <return> to see the next graphic.
Alternativaly the user can set the graphical parameter to have several
plots in one page. With default options for the arguments the maximum
number of plots (10) is produced and setting par(mfcol=c(5,2)))
will display them in the same page.
The “errors” for the plots are defined as
error = data - predicted
and the plots uses the color blue to indicate positive errors and
red to indicate negative erros.
Value
No value returned. Plots are produced on the current graphics device.
