sqldf不安装在Ubuntu 14.04上

Question

我正在尝试在Ubuntu 14.04机器上安装sqldf软件包,但是我收到以下错误:

Warning in install.packages :
  package ‘sqldf’ is not available (for R version 3.0.2)

我尝试按照其他帖子的建议安装库libpq-dev,但我仍然收到消息.

UPDATE

我正在尝试更新R,但我收到以下消息:

The following packages have unmet dependencies:
 r-base : Depends: r-base-core (>= 3.1.2-1precise0) but it is not going to be installed
          Depends: r-recommended (= 3.1.2-1precise0) but it is not going to be installed
          Recommends: r-base-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我尝试了本主题中的解决方案,但都没有奏效

Answer 1

查看包页面:

Depends:    R (? 3.1.0), gsubfn (? 0.6), proto, RSQLite (? 1.0.0)

正如错误消息明确指出的那样,您使用的旧版本R 3.0.2小于所需的3.1.0.

修复很简单:阅读Ubuntu特定的自述文件,进行调整以通过apt-getCRAN 安装(当前!!)R二进制文件作为.deb包- 您将立即获得R 3.1.2.

这将允许您安装当前的sqldf.
