Description Usage Format Examples
Simulated data for fast testing of the functions. A list contains integer responses, model matrix, distance matrix, and offset term.

y
Integer vector, the response variable, which is count data.
X
Numeric matrix, the model matrix contains covariate information.
offset
Numeric vector, vector for offset values.
dist
Numeric matrix, a matrix for pairwise distance.

#Here is a toy example for creating a data object that can be used for
#generating dat.obj for SpatialVS function

#simulate counts data
y=rpois(n=n, lambda=1)
#simulate covariate matrix
x1=rnorm(n)
x2=rnorm(n)
X=cbind(1, x1, x2)
#compute distance matrix from some simulated locations

loc_y=runif(n)
dist=matrix(0,n, n)
for(i in 1:n)

for(j in 1:n)
{
dist[i,j]=sqrt((loc_x[i]-loc_x[j])^2+(loc_y[i]-loc_y[j])^2)
}

#assume offset is all zero
offset=rep(0, n)
#assemble the data object for SpatialVS
dat.obj=list(y=y, X=X, dist=dist, offset=offset)
