[Bioc-devel] mzR 1.4.0 crashes R at loading

The last version of mzR crashes R-2.15.2 on windows (both 32 and 64 bit) at loading, i.e., R hangs after running "library(mzR)". I could confirm this in two computers (windows XP and 7).

The culprit might be Rcpp 0.10.0. I downgraded it to 0.9.15 (which I got from an old R installation) and now mzR works in both computers.

Coincidently, before a user reported me the error on windows, I had got an R crash on linux upon loading TargetSearch (my package which depends on mzR) which I fixed by re-installing both mzR and TargetSearch.

I suspect that mzR needs a version bump to force re-compilation. Maybe somebody can confirm this. I don't see any mzR error/warning in http://bioconductor.org/checkResults/2.11/bioc-LATEST/

Best regards,
