frg_sigmatrix: frg_sigmatrix

In lbusett/frgtool: Analyze Post Fire Vegetation Regeneration from Time Series of Summertime MODIS data

Description

Function used to perform statistical analysis in order to determine significance of scaled VI reductions in years following the fire.

• Starting from extracted time series, compute matrixes of p-values using FRG_Comp_Regr_Matrix. p-values matrixes contain result of the Wilcoxon test, computed using the selected number of reference pre-fire years and the selected minimum difference percentage.

• Matrixes of significances are then created using FRG_Significance_Analysis and saved.

Note: this is only a wrapper used to call the FRG_Comp_Regr_Matrix and FRG_Significance_Analysis functions)

Usage

frg_sigmatrix(in_file, out_file, opts)

Arguments

in_file	string File of scaled VI Time Series extracted for single-fire areas
out_file	string Basename for output files
opts	list of options passed from frg_fullprocessing()

Value

Saves a .RData file containing data needed to plot NDVIR time series for the different single-fire BAs
