[R] package argument to library as string

The help page for library says that:

package, help: name or character string giving the name of a package.

Yet, I don't seem to be able to use a string variable here.

Error in library(pkg) : There is no package called `pkg'

What am I misunderstanding? Why isn't pkg treated the same as "ts" by library()?
