[R] eigen vector question

Sorry to bother everyone, but I've looked in all of the help files and 
manuals I have and I can't find the answer to this question.  I'm doing 
principle component analysis by calculating the eigen vectors of a 
correlation matrix that I have that is composed of 21 parameters.  I have 
the eigen vectors and their values that R produced for me but I'm not sure 
how to tell which eigen vector/value corresponds to which parameter because 
when R produces eigen vectors it does so in decreasing order of 
significance, meaning that the eigen vector that explains the most of the 
variance is listed first, followed by the next eigen vector, etc etc. Any 
help would be appreciated. Feel free to write back if you need more 
information on my problem.  Thanks!
