Hi,
I want to know what is there returned values of 'lm'. 'class' and 'lm'
does not show that the returned value has the variable coefficients,
etc. I am wondering what is the command to show the detailed
information. If possible, I aslo want the lower level information. For
example, I want to show that 'coefficients' is a named list and it has
2 elements.
Try the str() function, it shows a summary of the structure of an object.
