Calculate the difference between dates (vectorized)

1	diffDate(chr.end.date, chr.start.date)

`chr.end.date`	End dates (in the same format), same length as chr.start.date
`chr.start.date`	Start dates (in format YYYY-MM-DD). Strongly recommend using toDate to get this format

Number of days (as numeric) between end date and start date

 
chr.start <- toDate(c('2017-01-01','2016-03-01','2015-01-01'))
chr.end <- toDate(c('2013-03-01', '2016-03-16', '2016-09-09'))
diffDate(chr.end, chr.start)
