  <p>I actually use a debian-stable system (v.7.6) and the next decision was to install "<em>r-cran-ggplot2</em>" in the console. 
  And when i install them, i think about i having this library, but when i write in Rstudio: <em>library(ggplot2)</em>, i take next message: <em>Error: package ‘ggplot2’ was built before R 3.0.0: please re-install it</em></p>
  
  <p>But i have a the up-to-date version - 3.1.1! 
  I really don't find any good answers for that question! PLeas, help!</p>
