When I tried to run the R console in Eclipse, I got this error:
....Please make sure that R package \'rj\' (1.1 or compatible) is installed...
None of the above worked for me, the only solution that installed rJava on Linux Ubuntu without any problems was to pass RScript command after installation of the base R:
rJava
RScript
$ sudo Rscript -e 'install.packages("rJava", repos = "http://cran.r-project.org/")'
