compressData: Compress sample data frame

In USGS-R/EGRET: Exploration and Graphics for RivEr Trends

Compress sample data frame

Description

Using raw data that has at least dateTime, value, code, populates the measured data portion of the Sample dataframe used in EGRET. ConcLow = Lower bound for an observed concentration ConcHigh = Upper bound for an observed concentration Uncen = 1 if uncensored, 0 if censored

Usage

compressData(data, verbose = TRUE)

Arguments

data	dataframe contains at least dateTime, code, value, columns in that order. If there are more than the initial date, code, value...it combines the data is combined as using interval censored concepts.
verbose	logical specifying whether or not to display progress message

Value

data frame returnDataFrame data frame containing dateTime, ConcHigh, ConcLow, Uncen

Examples

dateTime <- c('1985-01-01', '1985-01-02', '1985-01-03')
comment1 <- c("","","")
value1 <- c(1,2,3)
comment2 <- c("","<","")
value2 <- c(2,3,4)
comment3 <- c("","","<")
value3 <- c(3,4,5)
dataInput <- data.frame(dateTime, comment1, value1, 
      comment2, value2, 
      comment3, value3, stringsAsFactors=FALSE)
compressData(dataInput)
