To whom it may concern,

I'm unable to install XCMS (release38) because mzR can not be loaded

install_github(repo="sneumann/xcms",ref="RELEASE_3_8")

Return:

Error: package or namespace load failed for 'mzR':
 .onLoad failed in loadNamespace() for 'mzR', details:
  call: fun(libname, pkgname)
  error: (converted from warning) mzR has been built against a different Rcpp version (1.0.0)
than is installed on your system (1.0.1). 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 support forum at 
https://support.bioconductor.org/. For details see also
https://github.com/sneumann/mzR/wiki/mzR-Rcpp-compiler-linker-issue.

Could you first try loading from the Bioconductor repository rather than github

BiocManager::install("xcms")
