how do you convert a factor that has 3 digits miliseconds to datetime in R?

Question

I time a t object like this:

t<-c(\"2016-10-19 00:00:00.000\")

I need to convert to POSIXct as this:

as.POSIXct(t, format=\"         


        

Answer 1

You could use lubridate too :

library(lubridate)
t<-c("2016-10-19 00:00:00.000")
ymd_hms(t)
#> [1] "2016-10-19 UTC"
