Examples

  • add squared values
    Suppose we have a reference ASCIItable containing data to which we want to add the squared values of column » y «.
    2 head
    # reference ASCIItable
    x y
    1 1
    2 3
    3 4
    
    The lookup table contains
    2 head
    # lookup ASCIItable
    value squared
    1      1
    2      4
    3      9
    4     16
    5     25
    

    >  addLinked --link y value --asciitable lookup --label squared < reference
    
    yields
    3 head
    # reference ASCIItable
    # addLinked --index y value --asciitable lookup --label squared
    x y squared
    1 1 1
    2 3 9
    3 4 16
