Converts date and hour to internal time format.
emr_date2time(day, month, year, hour = 0)vector of days of month in [1, 31] range
vector of months in [1, 12] range
vector of years
vector of hours in [0, 23] range
Vector of converted times.
This function converts date and hour to internal time format. Note: the earliest valid time is 1 March 1867.
Note: if one of the arguments ('day', ...) is a vector, then the other arguments must be vectors two of identical size or scalars. Internally a data frame is built out of all the vectors or scalars before the conversion is applied. Hence rules for data frame creation apply to this function.
