Hello, I'm trying to install the IsotopicLabelling package in RStudio using:

install_github("RuggeroFerrazza/IsotopicLabelling", build_vignettes = TRUE) 

The installation requires to loading of the mzR package. I get the following error message during the install:

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 (
than is installed on your system (1.0.5). 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 For details see also
Error: package 'mzR' could not be loaded
Execution halted
ERROR: lazy loading failed for package 'IsotopicLabelling'

The output of sessionInfo() is:

The warning about the mzR/Rcpp versions can be ignored. Unfortunately, it is (if I'm not mistakenbeing) converted to an error by install_github(). I see two options

  1. First install mzR with BiocManager::install("mzR") and ignore the warning. Then proceed with the installation of RuggeroFerrazza/IsotopicLabelling.

  2. Set the environment variable Sys.setenv(R_REMOTES_NO_ERRORS_FROM_WARNINGS="true") before using install_github().
