Hello,

I am trying to load proteomics '.raw' files into R with the mzR package, but I got an error message that it fails. I think it has something to do with the Rcpp version, because when I load the library I get a comment about the Rcpp version. I don't know how to fix it, any advice? Thanks in advance!

Ben

Here the code:

> library(mzR)
Loading required package: Rcpp
Warning message:
In fun(libname, pkgname) :
  mzR has been built against a different Rcpp version (0.12.6)
than is installed on your system (0.12.7). 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

Indeed, mzR doesn't support vendor binary files. It supports all major open formats such as mzML, mzXML, ... You can convert your raw file into any of these using the msconvert software from proteowizard [1].

Best wishes,

Thank you for your quick reply, Laurent.

Do I understand correct that it is not possible to do the whole analysis in R then?

Kind regards,

Ben

Not sure what your whole analysis is, but once you have converted your files, there's a lot you can do in R. But possibly not everything. Have a look at the RforProteomics package vignettes for an overview. Best wishes, Laurent
