Details

Change demand data in various ways. Ways include replacing any number of 0 values with a replacement number (or remove them completely), removing price and consumption at free, replacing free with some number. This will soon replace ReplaceZeros and certain arguments in FitCurves.

Examples

## Change just the first instance of 0 within each unique value of id with .1
ChangeData(apt, nrepl = 1, replnum = .1)
