Sorry for using "parameters" when I meant "objects." I also wasn't
sufficiently clear about what I'm trying to do.
Your suggestion produces a single object, "parameters." What I want are 26
objects, a , b, c, ... whose values are df$values, which in my case are

You say you want "parameters", but that's not an R type. So here's one way,
but it might not be what you're looking for.
df <- data.frame(names=letters, values=1:26) parameters <- df$values
names(parameters) <- df$names
