[R] In fact this is a Stats question, but... "The return."

*Thanks* all those who took the time to help me (even if the  
"question" was not related to - the use of - R).

Now I think I can soundly make my point w/ the referee (can I use your  
replies? If so I intend to properly cite its use?!?).

ps - Sorry for not explaining the "biological details" of my posting:  
RNA/DNA is the ratio of RNA content to DNA content obtained for  
individual fish larvae (plus for each one I noted if it had visible  
prey items in the gut or not, thus the levels Prey and Empty of factor  
Gut); and sl is the standard length (distance from the tip of snout to  
the posterior extremity of the hypurals, the expanded bones at the end  
of the backbone that support the caudal fin, in mm) of the specimens.  
In the MS, I consider the relationship RNA/DNA to sl to be  
biologically irrelevant (due to the very low r2) although  
statistically significant. Furthermore, no effect of gut content upon  
that relationship is significant (facilitating further analysis of  
pooled data).
