I have the following DF:
MATRICULA <- c('111','222','333','444','555')
DATA_INICIO <- c('10/12/2017','31/12/2014',
'30/06/2015','20/11/2016','01/04/2014')
DATA_FIM <- c('10/12/2017', '01/01/2015', '02/07/2016', '03/12/2016',
'13/04/2014')
DADOS <- data.frame(MATRICULA,DATA_INICIO, DATA_FIM).
How to include a date difference column (in days) between the two dates (DATA_FIM
(-) DATA_INICIO
)?
