I need to repeat the sequence of values found in the "size" and "mass" columns within each tank. However, the number of repeats for each tank's sequence will differ (again in no particular pattern). I have another data frame (data frame 2) that contains the number of repeats for each tank's sequence, and it looks something like this even watching : Tutuapp 9apps Showbox
#code for making data frame 2
tank<-c(1,2,3,4)
rpeat<-c(3,1,2,2)
df2<-data.frame(cbind(tank,rpeat))
