Usage

1
limit_days(data, no_days, election_data, pv, election, election_date, ...)

Arguments

data

[data.frame()]
data frame of a pollyvote object.

no_days

Details

If limit_days is called like: limit_days(pv$data, no_days = 10, election_date = "Y-M-DD") and if pv object is not supplied, then election_date will not be validated whether it is existing election date in the pollyvote object. Therefore, it is more safe for if pollyvote object is also supplied as an argument (e.g. limit_days(pv$data, no_days = 10, pv = pv, election_date = "Y-M-DD")).

Value

the data set limited to the number of days before the election.
