Another Newbie Question sorry:

I am trying to apply a function a dataframe and could use some help:


Assuming, dim(df) = (10,2) say, I would like to apply a function that looks
at each row in turn and returns a list (dim =(10,1)) using the columns as
inputs to the function, but with no INDEX stuff that the by() function
refers to.

For a simple function x+y I know in Mathematica it would be this;

Table[df[[i,1]]+ df[[i,2]],{i,1,10}]

Of if the function was defined is would read;

Table[f[df[[i,1]], df[[i,2]]],{i,1,10}]

Thanks for help in advance

Glenn
