2 functions with same name - what to do to get the one I want

There seems to be 2 functions call ecdf...

http://lib.stat.cmu.edu/S/Harrell/help/Hmisc/html/ecdf.html
Apparently that used to be its name and that some time in the  
intervening 10 years the name was changed to Ecdf. The Statlib  
repository has rather ancient version of the Hmisc documentation.  
Notice that it gives Harrell's UVa address. You should not use that  
repository for documentation. Use the RSiteSearch:

http://search.r-project.org/cgi-bin/namazu.cgi?query=ecdf&max=100&result=normal&sort=score&idxname=functions
