Help functions.

Description

Help function used in other functions.

Usage

absIncrease(data, m1 = 10, m2 = 10, gfun = mean)
PGC(data, m1 = 10, m2 = 10, gfun = mean)
PGCreleases(change, criteria = 0.2)
PGCreleasesSplechtna(change, criteria = 0.5)
priorGrowth(data, m1 = 10, m2 = 10, gfun = mean, dom1 = 0)
writeReleaseStats(release_list, mytext)
removeMajorFromModerate(mod,maj,zero,on)
relListToDataFrame(release_list,data)

Arguments

data	Data frame returned by read.* function of dplR.
m1	Determines the number of years to be averaged (including target year) for period prior the potential releas.
m2	Determines the number of years to be averaged (not including target year) for period after the potential releas.
gfun	Determines if M1 and M2 values are mean or median for selected period.
criteria	Threshold for detection of moderate release.
change	Percentage growth change.
dom1	If prior growth (dom1=0) or m1 is computed (dom1=1).
release_list	List of releases per tree.
mod	List of moderate releases per tree.
maj	List of major releases per tree.
zero	Value for the beginning of the list.
on	List of growth changes per tree.
mytext	Prefix of the info text.
