CAVIAR is a package that allow processing, visualisation and analysis of data coming from cambial activity and wood formation monitoring studies.
CAVIAR contains 3 functions: computeBootstrapTest, computeCriticalDates, plotWoodCalendar.
The developed functions require input data files as semicolon separated value text files (i.e. CSV format).
The columns names are imposed but not the order. That means that the input table may contain a free number of columns, as long as the compulsory columns, identified by their headers, are provided to the function.
Missing values are coded "NA" in the data table.

Examples

# Loading the example dataset:
data(AMA2006)

# Computing wood formation critical dates for firs and pines:
Fir.cdd <- computeCriticalDates(AMA2006[AMA2006$Sp=="ABAL", ])
Pine.cdd <- computeCriticalDates(AMA2006[AMA2006$Sp=="PISY", ])

# Visualising wood formation critical dates and durations on the screen for firs:
plotWoodCalendar(Fir.cdd, plotype=4)

# Testing if pines start xylogenesis before firs
computeBootstrapTest(Fir.cdd$bE, Pine.cdd$bE)
