Hi,

I'm getting the following error message when I try to load MSGFplus on Mac OSX

​> library("MSGFplus")
Error: package or namespace load failed for ‘MSGFplus’:
 .onLoad failed in loadNamespace() for 'MSGFplus', details:
  call: if (as.numeric(sub(".*\"\\d\\.(\\d).*", "\\1", javaVersion[1])) < 
  error: missing value where TRUE/FALSE needed
In addition: Warning message:
In fun(libname, pkgname) : NAs introduced by coercion

I found the offending line of code in a file (zzz.R).  Tried commenting out the line and compiling package from source but still does not work.

All of the RforProtemics package works swimmingly on Ubuntu 16.04 (including MSFGplus).

Thanks for your help.

Darren

This was patched on Github in the last week https://github.com/thomasp85/MSGFplus/pull/13

I don't know if it's made its way it the version on Bioconductor yet, but you can install the Github version with:

BiocInstaller::biocLite('thomasp85/MSGFplus')
