How to add a new row in to an existing data set in R Language?

Hi,

Hi Ista Zahn,
                             Thanks for your advice. Please see the
following Image.

To me this example looks plain wrong. You end up with a row that
contains the date of birth for subject 104 and the date of informed
consent for subject 105.

If this really is the situation you face, I suggest correcting the ID
before merging.

 i am expecting the result should same in the image.

OK, then fix your ID numbers and use merge(DF1, DF2).

Best,
Ista
