get_param: Get parameters from curve fitting result

In phenofit: Extract Remote Sensing Vegetation Phenology

Get parameters from curve fitting result

Description

Get parameters from curve fitting result

Usage

get_param(x)

## S3 method for class 'list'
get_param(x)

## S3 method for class 'fFITs'
get_param(x)

## S3 method for class 'fFIT'
get_param(x)

Arguments

x	fFITs object returned by curvefit(), or list of fFITs objects

Value

A list of tibble with the length being equal to the number of methods. Each line of tibble cotains the corresponding parameters of each growing season.

Examples

library(phenofit)
# simulate vegetation time-series
FUN = doubleLog.Beck
par  = c( mn  = 0.1, mx  = 0.7, sos = 50, rsp = 0.1, eos = 250, rau = 0.1)
t    <- seq(1, 365, 8)
tout <- seq(1, 365, 1)
y <- FUN(par, t)
methods <- c("AG", "Beck", "Elmore", "Gu", "Zhang") # "Klos" too slow
fit <- curvefit(y, t, tout, methods) # `fFITs` (fine-fitting) object 
fits <- list(`2001` = fit, `2002` = fit) # multiple years

l_param   <- get_param(fits)
d_GOF     <- get_GOF(fits)
d_fitting <- get_fitting(fits)
l_pheno   <- get_pheno(fits, "AG", IsPlot=TRUE)
