[R] Copy dataframe for another

[R. Michael Weylandt]

What goes wrong? Your code isn't reproducible and you didn't give an
error message. I'd mention that "d <- Null" does not assign NULL to d
which might lead to a dimension mismatch at some point. Also,
something about your loop syntax seems funny: you are looping over
rows but selecting columns of your data frame -- seems dangerous.

Can you post a minimal working example including data (with dput()) ?
