runsNAltraj
performs a runs test to detect any autocorrelation
in the location of missing relocations, for each burst of an object of
class ltraj
.
summaryNAltraj
returns a summary of the number and proportion
of missing values for each burst of an object of class
ltraj
.
plotNAltraj
plots the missing values in an object of class
ltraj
against the time.
