This is the correct behaviour of eshell:

/scp:slbps0:/root $ which env
eshell/env is a compiled Lisp function in `esh-var.el'

If you want the environment of your remote eshell session, you shall
call /bin/env instead.

With Tramp means, you could do

  (add-to-list 'tramp-remote-path "/usr/local/R-2.14.0/bin")

Alternatively, you could instruct Tramp to preserve the path settings of
your remote account:

  (add-to-list 'tramp-remote-path 'tramp-own-remote-path)
