getFrcSum: getFrcSum

In USGS-R/USGSHydroOpt: Tools for optical data analysis

getFrcSum

Description

Computes the fraction of the sum of two signals from optical data as: Fraction = variable 1 / (variable 1 + variable 2)

Usage

getFrcSum(dataSummary, sigs, grnum)

Arguments

dataSummary	dataframe with summary absorbance and fluoresence data.
sigs	signals vector of variable names in dataSummary for generating fractions
grnum	character column name that defines the column with sample names in the dataSummary dataframe. These names are used to merge fraction data into the summary dataframe.

Value

dataSummary dataframe with the additional columns of spectral fractions computed using getFrcSum

Examples

dataSummary <- dfsummary
sigs <- fractionSignals
grnum <- "GRnumber"
test <- getFrcSum(dataSummary,sigs,grnum)
