如何在Debian Jessie（8.8）上安装更新的R-packages？

Question

On Debian Jessie (8.8), the most up-to-date R package isn't enough for using some Jupyter-notebook functions (like rpy2 ), so I am trying to get R>=3.3 version. The current version is:

R version 3.1.1 (2014-07-10)    

Here is an useful link provided by a stackoverflow user: https://cran.r-project.org/bin/linux/debian/ , but even with it, I don't know how to get the newer R-version.

Would you help me please?

EDIT

Not sure if helps, but here is what I have in /etc/apt/sources.list

# deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160315-14:54]/ jessie contrib main non-free

## Repositorio oficial de Debian GNU/Linux
deb http://ftp.debian.org/debian/ jessie main contrib non-free

deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free

You can upgrade r package from :

1) Backports repository : (the 3.3.3 version)

Add the following line to your sources.list :

deb http://deb.debian.org/debian jessie-backports main contrib non-free

Save then install r :

apt-get update
apt-get -t jessie-backports install r-base r-base-dev

2) CRAN repository (the 3.4.3 version)

Follow the steps described on the official documentation :

For a backport of R 3.4.3 to jessie, please add something like

deb http://<favourite-cran-mirror>/bin/linux/debian jessie-cran34/

to the file /etc/apt/sources.list on your computer. You need to substitute <favourite-cran-mirror> by one of the mirror URLs listed in the mirror list .

Secure APT

Before installing the package from CRAN repository , You need to import the singing key released by Johannes Ranke <jranke@uni-bremen.de> ( see the secure-apt )

e,g:.

echo deb https://mirrors.sorengard.com/cran/bin/ldebian jessie-cran34/ >> /etc/apt/sources.list
apt-key adv --keyserver keys.gnupg.net --recv-key 'E19F5F87128899B192B1A2C2AD5F960A256A04AF'
apt-get update
apt-get install r-base r-base-dev
