Undeclared package ‘LiblineaR’ in Rd xrefs
File ‘LiblineaR.ACF/libs/LiblineaR.ACF.so’:
  Found ‘vsprintf’, possibly from ‘vsprintf’ (C)
    Objects: ‘linear.o’, ‘tron.o’
File ‘LiblineaR.ACF/libs/LiblineaR.ACF.so’:
  Found no calls to: ‘R_registerRoutines’, ‘R_useDynamicSymbols’

Compiled code should not call entry points which might terminate R nor
write to stdout/stderr instead of to the console, nor use Fortran I/O
nor system RNGs nor [v]sprintf.
It is good practice to register native routines and to disable symbol
search.
