Meaning of %%

Thanks a lot for the guidance. 

Before posting this query, I had tried following things.

> ?%%
Error: unexpected SPECIAL in "?%%"
> ??%%
Error: unexpected SPECIAL in "??%%"

I also tried search.r-project.org and tried to search there also, but no luck.

> help("%%") GIVES ME

In addition: Warning message:

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
