[BioC] Question about turning strings into variable names in R

[J.delasHeras at ed.ac.uk]

Hi,

I have a situation where I have a vector of variable names. If I call  
any of them, I get a text string (the name is surrounded by ""). How  
can I use that as a variable name again?

For instance, I have objects a, b and c, and a vector v<-c("a","b","c").
If I want to return the contents of a, I can't do just v[1], because  
that only shows "a"...
Is there a simple way to indicate that "a" should be taken as the name  
of an object, and not as a string? If so, I haven't found it...

thanks!

Jose
