Keywords
spatial
Usage
p.adjustSP(p, nb, method = "none")
Arguments
p
vector of p-values
nb
a list of neighbours of class nb
method
correction method as defined in p.adjust: "The adjustment methods include the Bonferroni correction ('"bonferroni"') in which the p-values are multiplied by the number of comparisons. Four less conservative corrections are also included by Holm (1979) ('"holm"'), Hochberg (1988) ('"hochberg"'), Hommel (1988) ('"hommel"') and Benjamini & Hochberg (1995) ('"fdr"'), respectively. A pass-through option ('"none"') is also included."
Value

A vector of corrected p-values using only the number of neighbours + 1.
