climate.anom.dendro.season: Seasonal Data

In dplRCon: Concordance for Dendroclimatology

Description

Changes monthly climate data to seasonal climate data.

Usage

climate.anom.dendro.season(climate.data, year1, year2, year.start, is.anomaly)

Arguments

climate.data	This is a matrix, normally loaded into R in CSV form with the columns: year, jan, feb, mar,..,dec
year1	is the start of the period used to calculate climate anomalies.
year2	is the end of the period used to calculate climate anomalies.
year.start	is the start date of the climate data,
is.anomaly	accepts true or false. True will calculate the anomalies; departures from the mean from the period specified in year1 and year2

Value

Return a matrix of time series with col names season for the seasons including lagged seasons; "SON_2","DJF_2","MAM_2","JJA_2","SON_1","DJF_1","MAM_1", "JJA_1","SON","DJF","MAM","JJA";
