flexFN: Flexible Flow Normalization

In USGS-R/EGRETextra: Exploration and Graphics for RivEr Trends (EGRET) Extra Code

Description

Flexible Flow Normalization

Usage

flexFN(eList, dateInfo, sampleStart = "sampleSegStart",
  flowStart = "flowSegStart", flowEnd = "flowSegEnd")

Arguments

eList	named list with at least the Daily, Sample, and INFO dataframes
dateInfo	data frame with 3 columns, their names defined by sampleStart, flowStart, flowEnd
sampleStart	integer vector of start years (water) for each FN conc/flux segment
flowStart	integer vector of start years (water) for flow normalization
flowEnd	integer vector of end years (water) for flow normalization

Examples

library(EGRET)
eList <- Choptank_eList
eList <- setUpEstimation(eList)
sampleSegStart <- c(1980,1990,2000)
flowSegStart <- c(1980,1985,1992)
flowSegEnd <- c(1994,2004,2011)
dateInfo <- data.frame(sampleSegStart, flowSegStart, flowSegEnd)
eList <- flexFN(eList, dateInfo)
plotFluxHist(eList)

eList <- Choptank_eList
