Arguments for use with |
col.key |
A vector of colors in hexadecimal format. |
cutoffs |
A vector of cut points for assigning the colors in |
cutoffs
must be a vector of increasing values of the same length as col.key
plus 1. cutoffs
divides the residual values in x$residuals
into a number of intervals equal to the number of colors in col.key
. The colors are assigned to the intervals in order, e.g. the first color in col.key
will be plotted in the bins defined by the spatial grid in x$grid
that contains a residual that falls anywhere in the first interval (lower bound inclusive, upper bound exclusive).
Default col.key
is a vector of 100 heat
colors in reverse. Default cutoffs
is a vector of 101 equally spaced points that range from the minimum residual in x$residuals
, minus a very small number, to the maximum residual, plus a very small number.
The default col.key
and cutoffs
may not be useful if the residuals are highly skewed. In this case, there should be more values in cutoffs
where the residuals are most dense.
These are simply default plots for quick illustration of the residuals, and may or may not be useful for detailed analysis of the residuals.
