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


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
