I apologize if you have already seen my question.  I am new to the mailing list 
and I did not get any responses the first time I posted my question.  However, 
I am not sure my post went through.  
 
Here is my situation:  
I have a spreadsheet with columns of fish species (text) and length (numbers).  
In the fish species column I have 5 different fish.  I want R to calculate the 
mean length and standard error for each species. 
  
I tried using the stats functin with 
stats(fishdata, by=species) 
  
R told me it could not find function stats.  Is there a library I need to 
install to get stats to work?
