Jane,

Two separate questions. The answer to the first is "yes". This you could
have found, for instance, with:

??empirical

which gives you link to ecdf or empirical cumulative distribution function.
See its examples and help.

The second question can be answered without the use of ecdf(), although
ecdf() returns a function that can be used to answer to your question.
