[BioC] warning message of lumiR

These warning messages are not a problem.
For the first warning message, it is because you included "lumiHumanAll.db"
in the lumiR. For the new version of lumi Annotation packages, like
"lumiHumanAll.db", they do not include ID mapping information, so you don't
need to include it in the lumiR (see example in the new version of
vignette). You just need to type:
The lumiR function will automatically convert the probe sequences (if exist)
For the second warning message, it is because Illumina gave different IDs
for the same probe sequence. In this case, lumiR will average them
(basically there are more beads for the same probe). So it is not a problem.
