recogniseDateTime: Recognise date-time variables when month and year are known...

In nyilin/QcDM: Quality Care for Diabetes Mellitus

Description

Recognise date-time variables when month and year are known (otherwise there is no way to differentiate date and month)

Usage

recogniseDateTime(dateTime, month, year, time_dummy = "11:11:11")

Arguments

dateTime	A vector of strings indicating the date and time that satisfy the assumptions specified in the Details section.
month	A number (1 to 12) indicating the month this time point is in.
year	A number (with 4 digits) indicating the year this time point is in.
time_dummy	A dummy time assigned to date-time variables when time is not available. Default is 11:11:11.

Details

Assumptions made on the format of input time are: (i) only "/" or "-" is used to separate date, month and year, and no mixture of the two symbols in a single time variable; (ii) only ":" is used to separate hour, minute and second, and the order is always in "h:m:s" (second can be missing, but not minute or hour); and (iii) a dateTime variable should contain both date and time.

Value

Returns a string vector of the format
