Move row to top of table

Question

I am wondering if it is possible to move one row from bottom to top of a table. When I use the code I have so far,

dt[nrow(dt)+1,] <- rbind(c(\"\",\"\",\"         


        

Answer 1

There are a few ways but here are two easy ones:

a <- data.frame(x = 1:10, y = 20:29)
a <- a[c(10,1:9),]
a

##Or

a <- data.frame(x = 1:10, y = 20:29)
a <- rbind(a[10,],a[1:9,])
a
