R: how to filter a timestamp by hour and minute?

Question

I am struggling with the following example

time = c(\'2013-01-03 21:59:21.549\', \'2013-01-04 22:00:21.549\', \'2013-01-05 22:01:21.222\', \'2013-01-06 22:06         


        

Answer 1

I guess this solves your problem:

library(dplyr) 

result <- data %>%  
  mutate(time2 = format(time, format="%H:%M:%S")) %>%
  filter(time2 >= "21:59:00" & time2 < "22:02:00") %>%
  select(-time2)
