Hi,

If I've a dataframe like this:

a <- data.frame(a=c(14,21,14,4), b=c(21,45,23,11))

print(a)

   a  b
1 14 21
2 21 45
3 14 23
4  4 11

I can delete the first row with:

b = a[-(1),]

print (b)

   a  b
2 21 45
3 14 23
4  4 11

Now, can I add to dataframe b the row that I've deleded?

print (b)

   a  b
1 14 21
2 21 45
3 14 23
4  4 11



Best Wishes,

Alfredo
