Hi everyone,

I have used the newest version of R (3.2.2 and 3.2.3) and Bioconductor (3.2), but I still could not successfully load the package mzR, it seems that it was one of the issues many people had mentioned -- compiler/linker. Below is the error message and the sessionInfo(). Note that I used R 3.2.3 first although the below was the output when I tried R 3.2.2.

> library(mzR)
Error : .onLoad failed in loadNamespace() for 'mzR', details:
  call: description[["RcppModules"]]
  error: subscript out of bounds
In addition: Warning messages:
1: In fun(libname, pkgname) :
  mzR has been built against a different Rcpp version (0.12.1)
than is installed on your system (0.12.3). 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

I hope the output is not too messy to read. Look forward to hearing some helpful advice.

Many thanks in advance,

I don't think that the problem is the Rcpp version. The error is

Error : .onLoad failed in loadNamespace() for 'mzR', details:
  call: description[["RcppModules"]]
  error: subscript out of bounds

which is new however to me.

I have nevertheless committed a new mzR version 2.4.1, which will be build with Rcpp 0.12.3. Please try to install it in about 24 hours and let us know if this helps.
