When I tried to run r console in eclipse,got this error:
--------------------------------------------------------------------------------------------------
....Please make sure that R package 'rj' (1.1 or compatible) is
installed...
So I tried to intall it in R console like this:
--------------------------------------------------------------------------------------------------
install.packages(c("rj", "rj.gd"),
repos="http://download.walware.de/rj-1.1";)
got this error:
--------------------------------------------------------------------------------------------------
** testing if installed package can be loaded
Error : .onLoad failed in loadNamespace() for 'rj.gd', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object
'/home/alex/R/x86_64-pc-linux-gnu-library/2.15/rj.gd/libs/rj.gd.so':
libjvm.so: cannot open shared object file: No such file or
directory
Error: loading failed
Execution halted
ERROR: loading failed
and I found when installing rjava like this: install.packages("rJava")
will get similar error:
--------------------------------------------------------------------------------------------------
