To whom it may concern:
Here I get this error when I open new R session:

"During startup - Warning messages:
1: In fun(libname, pkgname) :
   mzR has been built against a different Rcpp version
 than is installed on your system. This might lead to errors
 when loading mzR. If you encounter such issues, please send
 a report, including the output of sessionInfo() to the Bioc
 mailing list -- http://www.bioconductor.org/help/mailing-list.
2: Class "C++Object" is defined (with package slot ‘Rcpp’) but no metadata object found to revise subclass information---not exported?  Making a copy in package ‘.GlobalEnv’"

I have installed xcms and metaXCMS packages but I encounter several errors when I try to run metaXCMS. 

I installed/uninstall R several times. IS there a way of fixing mzR/Rcpp problem?

I appreciate any help\
All Best,
