strange... I think something is wrong with the compilation, since as far
as I know, the package `base' should be loaded automatically by starting
R...

To cite R in publications use:

   R Core Team (2014). R: A language and environment for statistical
   computing. R Foundation for Statistical Computing, Vienna, Austria.
   URL http://www.R-project.org/.

A BibTeX entry for LaTeX users is

   @Manual{,
     title = {R: A Language and Environment for Statistical Computing},
     author = {{R Core Team}},
     organization = {R Foundation for Statistical Computing},
     address = {Vienna, Austria},
     year = {2014},
     url = {http://www.R-project.org/},
   }

We have invested a lot of time and effort in creating R, please cite it
when using it for data analysis. See also ?citation("pkgname")? for
citing R packages.
