plotBoundary {TRADER} | R Documentation |
Plot boundary line.
Description
Plot boundary line.
Usage
plotBoundary(boundaries, x, y, boundary, rsq = NULL,

prefix = NULL)
Arguments
boundaries |
Data frame with |
x |
x coordinates of all priors. |
y |
y coordinates of all priors. |
boundary |
Boundary line function of one argument, eg. |
rsq |
R square of the fit. |
criteria |
Threshold for detection of moderate release |
criteria2 |
Threshold for detection of major release. |
store |
If to save results on files. |
storedev |
Format for saving the graphical outputs, eg. pdf or jpeg. |
prefix |
Prefix of saved files. |
Details
Boundary-line method scales the percent growth change of Nowacki & Abrams (1997) according to growth rate prior to disturbance. In their example, Black & Abrams (2003) defined moderate and major releases as those falling within 20-49.9%, and 50-100% of the boundary line, respectively. Advantage of the boundary-line is standardization, which takes into account the relationships among tree age, size, and canopy class determining radial growth rate (Black et al. 2004). On the downside, Black et al. (2009) suggest approximately 50000 ring width measurements is necessary for boundary line determination for a given species (Black et al. 2009).
Value
Plot boundary line and priors.
