I'm trying to install sqldf package in an Ubuntu 14.04 machine, but I'm getting the following error:
Warning in install.packages :
package ‘sqldf’ is not available (for R version 3.0.2)
I tried to install the library libpq-dev as suggested from other post, but I still receive the message.
UPDATE
I'm trying to update R, but I'm getting the following message:
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.
I tried the solutions in this topic, but none worked
