Does this work?
data(cars)
cars2 <- cars
cars2[2:nrow(cars)+1,] <- cars2[1:nrow(cars),]

I have a large data frame 48:2185 with different numbers.
I would like to add only one row at the very top of my data frame with
0's or NA's.
I don't know which approach to use. Should i create 2 different data
frames and merge them? Ive also tried the rbind command with no luck.
I would appreciate some help to achieve what I'm trying to create.
Thanks!
