| runsNAltraj {adehabitat} | R Documentation |
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.

runsNAltraj returns a list of objects of class
randtest (if a burst does not contain any missing value, the
corresponding component is NULL).
