[R] installing r on ubuntu ?

[Witold E Wolski]

Hi,

trying to install newest R on ubuntu

I follow the instructions at:
 http://cran.at.r-project.org/bin/linux/ubuntu/


I added:

deb http://cran.r-mirror.de/bin/linux/ubuntu saucy/

to:
/etc/apt/sources.list


running :

sudo apt-get update

produces :
W: GPG error: http://cran.r-mirror.de saucy/ Release: The following
signatures couldn't be verified because the public key is not
available: NO_PUBKEY 51716619E084DAB9

??


regards
Witold
