CreateCalendarVariables: CreateCalendarVariables

Description

CreateCalendarVariables Rapidly creates calendar variables based on the date column you provide

Usage

CreateCalendarVariables(
  data,
  DateCols = NULL,
  AsFactor = FALSE,
  TimeUnits = "wday"
)

Arguments

data

This is your data

DateCols

Supply either column names or column numbers of your date columns you want to use for creating calendar variables

AsFactor

Set to TRUE if you want factor type columns returned; otherwise integer type columns will be returned
