Methods for class localsrq

methods_localsrq.Rd

The plot() function allows the user to plot significant observations. The print() function is used to print the number of runs in each localization. Additional information of expected values and standard deviation, z-value ans p-value is prited for each observation.

Usage

# S3 method for localsrq
print(x, ...)

# S3 method for localsrq
plot(x, ..., sf = NULL, coor = NULL, sig = 0.05)

Arguments

x

a localsrq object created by Q.test.

...

further arguments passed to or from other methods.

sf

optional argument for plot() method to include a sf object (default = NULL)

coor

optional argument for plot() method to include coordinates of points (default = NULL)

sig

significant level for each observation in plot() method. Default sig = 0.05

Value

No return value, called for side effects

rho <- 0.5
fx <- dgp.spq(p = p, listw = listw, rho = rho)

# Asymtotic version
lsrq <- local.sp.runs.test(fx = fx, listw = listw, alternative = "less")
