我想用ubuntu从3.0.3更新到3.1。我正在研究Ubuntu 14.04LTS，64位。
我做了以下事情：
cd /etc/apt/
sudo gedit sources.list
我添加了以下行：
deb http://cran.rstudio.com/bin/linux/ubuntu trusty/
然后：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install r-base
上传了一些文件。
然后我检查了R版本：
sudo R
version
platform x86_64-unknown-linux-gnu
arch x86_64
os linux-gnu
system x86_64, linux-gnu
status
major 3
minor 0.3
year 2014
month 03
day 06
svn rev 65126
language R
version.string R version 3.0.3 (2014-03-06)
nickname Warm Puppy
我还有3.0.3版本，有人可以帮我升级到3.1.2吗？

好的，我修好了。
在synaptic包管理器中，我看到R-3.1.2安装在以下目录中（可执行文件名为R）：/ usr / lib / R / bin / R
当我输入
which R
它返回：
/usr/local/bin/R
因此，R的来源与更新的路径不同。 我刚刚复制粘贴了新的可执行文件（位于/ usr / lib / R / bin /中的好目录/ usr / local / bin /）。
