data

dataframe contains at least dateTime, value, code columns

interactive

logical Option for interactive mode. If true, there is user interaction for error handling and data checks.

Examples

dateTime <- c('1985-01-01', '1985-01-02', '1985-01-03')
comment1 <- c("","","")
value1 <- c(1,2,3)
comment2 <- c("","<","")
