I'm not sure what you mean by "reuse".  All of the information for how
to set header arguments in available at (info "(org) Using header arguments")

system-level < buffer/subtree-level < language-level < code-block-level

Given that (:session . "*R*") will be used by default you could simply
remove it from your custom setting for org-babel-default-header-args.
