blankTime: Deletes the computed values during periods of time when there are no sample data

Description

This function is used when the data analyst believes that a gap in the sample data record is so long that estimates during that period are not reliable. This is only used for periods of several years in duration. For this period, the values of Conc, Flux, FNConc and FNFlux are all converted to NA.

Usage

blankTime(eList, startBlank, endBlank)

Value

eList named list with modified Daily data frame.

Arguments

eList

named list with at least the Daily dataframe

startBlank

character specifying starting date of blank period, input in quotes in yyyy-mm-dd format

endBlank

character specifying the ending date of blank period, input in quotes in yyyy-mm-dd format

Examples

startBlank = "2004-10-01"
endBlank = "2006-09-30"
eList <- Choptank_eList
eList <- blankTime(eList, startBlank, endBlank)
