I have two dates in date and time format.
Data1 <- 20/01/2018 20:33:58
Data2 <- 21/01/2018 20:23:48
The difference in hours is 23:49:50 . How is the calculation of this difference in R?
In addition, I need to know if this difference above is more or less than 24 hours. How do I do this check?
You can use the difftime function, but remember that the dates must be in Date-Time or Date .
To transform character into Date-Time :
Data1 <- "20/01/2018 20:33:58"
Data2 <- "21/01/2018 20:23:48"
# Converter
Data1 <- strptime(Data1, "%d/%m/%Y %H:%M:%S")
Data2 <- strptime(Data2, "%d/%m/%Y %H:%M:%S")
class(Data1)
> [1] "POSIXct" "POSIXt"
Calculate the difference:
difer <- difftime(Data2, Data1, units = 'hour')
> Time difference of 23.99722 hours
I do not know what context you want to use, but you can use if else to know if the difference is greater or less than 24h.
if(difer[[1]] > 24) {
"fazer algo se mais que 24"
}else{
"fazer algo se menos que 24h"
}
