Description Usage Arguments Value
A function to interpolate covariate values onto the fft grid, ready for analysis
1 2 | cov.interp.fft(formula, W, regionalcovariates = NULL,
pixelcovariates = NULL, mcens, ncens, cellInside, overl = NULL)
|
formula |
an object of class formula (or one that can be coerced to that class) starting with X ~ (eg X~var1+var2 *NOT for example* Y~var1+var2): a symbolic description of the model to be fitted. |
W |
an owin observation window |
regionalcovariates |
an optional SpatialPolygonsDataFrame |
pixelcovariates |
an optional SpatialPixelsDataFrame |
mcens |
x-coordinates of output grid centroids (not fft grid centroids ie *not* the extended grid) |
ncens |
y-coordinates of output grid centroids (not fft grid centroids ie *not* the extended grid) |
cellInside |
a 0-1 matrix indicating which computational cells are inside the observation window |
overl |
an overlay of the computational grid onto the SpatialPolygonsDataFrame or SpatialPixelsDataFrame. |
The interpolated design matrix, ready for analysis
