How to access single elements in a table in R

Question

How do I grab elements from a table in R.

My Data looks like this:

         V1     V2
1      12.448 13.919
2      22.242  4.606
3           


        

Answer 1

Maybe not so perfect as above ones, but I guess this is what you were looking for.

data[1:1,3:3]    #works with positive integers
data[1:1, -3:-3] #does not work, gives the entire 1st row without the 3rd element
data[i:i,j:j]    #given that i and j are positive integers

Here indexing will work from 1, i.e,

data[1:1,1:1]    #means the top-leftmost element
