An alternative is to inherit from the “r” package in “statistics.scm”.

    (define-module (my own packages)
      #:use-module (guix packages)
      #:use-module (gnu packages statistics)
      #:use-module (srfi srfi-1))
      
    (define-public my-r
      (package (inherit r)
        (name "my-r")
        ;; modify only the inputs here
        (native-inputs (alist-delete "texlive" (package-native-inputs r)))       
        (inputs (alist-delete "icedtea6" (package-inputs r)))))

Substitutes are downloaded from hydra only if hydra has been authorized
as a source for binary substitutes.  You can revoke permission for hydra
or temporarily disable the use of substitutes with the flag
‘--no-substitutes’.
