linelist2xts: Simple Date based aggregation based on the data.table...
In Hackout2/incidence: Computation and Visualisation of Incidence from Line Lists

Description Usage Arguments Details Value

The function allows to split by a single factor variable. More factors as well as factor interactions are currently not supported.

1	linelist2xts(formula, dateProjFun = identity, dRange = NULL, data)

`formula`	Formula of type LHSVar ~ RHSVar, where LHSVar is a column of class Dates and RHSVar is a column containing a factor variable
`dateProjFun`	Date projection function, i.e. how are dates projected down (i.e. monday, start of month, etc.). Result must be a Date again!
`dRange`	Vector of length two giving the start and stop dates, the actual range will be range(dateProjFun(dRange)).
`data`	data.frame containing the LHSVar RHSVar variables.

The formula has to be of the type LHSVar ~ RHSVar, where LHSVar is a column of class Dates and RHSVar is a column containing a factor variable. Currently, the formula is unrwapped manually. A better solution is to use formula syntax. Note: A multivariate time series for all levels of RHSVar (including NA if present) is generated.
