[R] Paste and namespace

[Fernando Henrique Ferraz Pereira da Rosa]

 Hi, my doubt is very simple. I'm sure I've seen someone using something
like this before, but unfortunatelly my searches in the archives were useless.
 Well, I have some objects called after a name that has a number attached to
it,
 varying. Let's say I have:
 > ls
   poly1 poly2 poly3 poly4 poly5 poly6 ...
 
 I would like to access these objects using a for(), in which I could do
something like paste("poly",i,sep=''). For i = 4, for instance I get
 > paste("poly",4,=sep'')
 [1] "poly8"
 Which is a string. What command should I use to 'access' the object named
by this string, ir order to do some useful things, like changing its value?

Thank you,
