x	A numeric vector.
nb	a neighbor list object for example as created by st_contiguity().
wt	a weights list as created by st_weights().
alternative	default "two.sided". Should be one of "greater", "less", or "two.sided" to specify the alternative hypothesis.
allow_zero	If TRUE, assigns zero as lagged value to zone without neighbors.
...	additional methods passed to spdep::globalG.test().

Value

an htest object

Examples
