Hi,
   
  How can I read data of unequal number of observations (rows) as is (i.e. without introducing NA for columns of less observations than the maximum. Example:
   
  A    B   C   D
  1    10  1   12
  2    10  3   12
  3    10  4   12
  4    10  
  5    10  
   
  Thanks in advance.
   
  Sachin
