Do you have the same version of Rcpp as root and as non root ?
You can use c++filt to demangle the name, e.g. what does this give you:
$ c++filt _ZN4Rcpp8internal14r_vector_startILi14EdEEPT0_P7SEXPREC
r_vector_start has changed in 0.10.1, i.e. it lost a template parameter,
which is likely to be the case here. I suppose you have two versions of
Rcpp installed;

The problem seems to be file privileges. When I run R as superuser, it
works. When I run as a normal user, I continue getting
Error in dyn.load(libLFile) :
unable to load shared object '/tmp/RtmpTFHtzm/file1d365e7eaf51.so':
/tmp/RtmpTFHtzm/file1d365e7eaf51.so: undefined symbol:
_ZN4Rcpp8internal14r_vector_startILi14EdEEPT0_P7SEXPREC
Note that the names of the undefined symbol is the same for all of the
ways and examples I have tested, which include:
cxxfunction (following the vignette)
cppFunction (following Hadley's tutorial)
R CMD INSTALL -l foo mypackage
where "mypackage" is created by Rcpp.package.skeleton("mypackage")
R CMD INSTALL -l foo somepackage.tar.gz
where "somepackage" is a package downloaded from CRAN which uses Rcpp.
I would very much appreciate a hint/suggestion as to which
folders/directories/paths I may need to check to get the file
permissions correct.
Does the name of the undefined symbol tell you anything? If you ignore
some characters, it reads
...Rccp.internal..r_vector_start...SEXPR..

That is with Rcpp from SVN but that shouldn't matter.
