Subject: [R] plotting the lognormal density curve


I am trying to plot a lognormal density curve on top of an 
existing histogram. Can anybody suggest a simple way to do 
this? Even if someone could just explain how to plot a 
regular normal density curve on top of an existing histogram, 
it would be a big help.

Also, is there some way to search through the R-help archives 
other than simple browsing?

Thank you so much. Your help and time is greatly appreciated.
