Adding missing rows

Question

The format of my excel data file is:

 day                 value
 01-01-2000 00:00:00    4
 01-01-2000 00:01:00    3
 01-01-2000 00:02:00    1
 01-01-2000 00:         


        

Answer 1

This is now completely automated in the padr package. Takes only one line of code.

original <- data.frame(
  day = as.POSIXct(c("01-01-2000 00:00:00",
                     "01-01-2000 00:01:00",
                     "01-01-2000 00:02:00",
                     "01-01-2000 00:04:00"), format="%m-%d-%Y %H:%M:%S"),
  value = c(4, 3, 1, 1))

library(padr)
library(dplyr) # for the pipe operator
original %>% pad %>% fill_by_value(value)

See vignette("padr") or this blog post for its working.
