Hi Joris,

Thanks for your help!

The data as requested:

structure(list(FROM = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L,

"HR", "DD", "MM", "YY", "ANIMAL", "DAY"), row.names = c(NA, 41L
), class = "data.frame")



The output should be as the original file is, but it should have an
additional column for 'TO_ID' 

I hope that makes sense? 

Cheers,
