Can't Uninstall or Fix MKL library for RRO

[Dwayne Paschall]

Ubuntu Linux 15.10.

I removed and re-installed RRO. No previous base R package installed. I previously had RRO and MKL installed then had to re-install RStudio for some other non-related problems. Now, MKL does't seem to work (error on starting R):

Error : .onLoad failed in loadNamespace() for 'RevoUtilsMath', details:

  call: fun(libname, pkgname)

  error: To use RevoUtilsMath you must first install the MKL Math Library.

 Visit http://mran.revolutionanalytics.com/download.

 If you have previously installed the MKL Math Library,

remove it and then re-install.

Error: package or namespace load failed for ‘RevoUtilsMath’

SO HERE IS THE PROBLEM:

1. I can't uninstall MKL because it says it is only for R version 3.2.2. The problem is that this is Exactly the version of RRO I have installed:

Revolution R Open 3.2.2

2. I can't install a clean version of MKL because the old/broken version is detected. It says to uninstall this first.

So I'm stuck in an infinite loop. I can't uninstall MKL to fix it (even though I had the RRO version it requires). I can't re-install it because it requires me to uninstall the bad/broken version first. Frustrating.

Any words of wisdom? Yes, I have a local library of packages in my home directory.

thanks

Hello,

Thank you for your report. It appears there is a defect in the uninstaller, but there is a simple workaround. After running the uninstall script, delete the RevoUtilsMath directory. Please let us know if that fixes your issue.
