I have a list of people...

v <- c("John", "Paul", "Annie")

and I want to distribute them recursively accross 14 different rooms.

df1 <- data.frame(ROOM = c("ROOM01", "ROOM02", "ROOM03", "ROOM04", "ROOM05", "ROOM06", "ROOM07","ROOM08", "ROOM09","ROOM10","ROOM11","ROOM12", "ROOM13", "ROOM14"),
                  PERSON = NA)


> View(df1)
> df1
     ROOM PERSON
1  ROOM01     NA
2  ROOM02     NA
3  ROOM03     NA
4  ROOM04     NA
5  ROOM05     NA
6  ROOM06     NA
7  ROOM07     NA
8  ROOM08     NA
9  ROOM09     NA
10 ROOM10     NA
11 ROOM11     NA
12 ROOM12     NA
13 ROOM13     NA
14 ROOM14     NA

So, my desired dataset would be like that

     ROOM     PERSON
1  ROOM01     John
2  ROOM02     Paul
3  ROOM03     Annie
4  ROOM04     John
5  ROOM05     Paul
6  ROOM06     Annie
7  ROOM07     John
8  ROOM08     Paul
9  ROOM09     Annie
10 ROOM10     John
11 ROOM11     Paul
12 ROOM12     Annie
13 ROOM13     John
14 ROOM14     Paul

Any help would be very appreciated! Thanks

We can use rep with length.out as number of rows (nrow) of the data, which will recursively replicate until it reaches the limit

df1$PERSON <- rep(v, length.out = nrow(df1))
