mzR and Rcpp version not compatible

[Thomas Pouplin]

Hello IDEOM users,

I've been using IDEOM a while ago and really enjoyed it.

I recently had a new dataset (lipids) to process and wanted to have a go. But since the R update to version 3.3.2, it does not work at all.

This is the message I got from the R console after trying to use the mzmatch script (R - 32 bits):

> source ("http://puma.ibls.gla.ac.uk/mzmatch.R/install_mzmatch.R")

2: In install.packages(pkgs = "mzmatch.R.tar.gz", repos = NULL, type = "source") :

I've tried to downgrade the Rcpp package to previous versions but none of them work ...

Any advice from here ?

Thanks

Thomas

Downgrading R from 3.3.2 to 3.3.1 did the trick.

I still had plenty of issues but manual package installation using the tar.gz files worked ...

The rJava issue has been painful to fix and was somehow locking everything but using IDEOM in R 32 bits was OK (although I'm using windows 7 pro 64 bits and the newest Java 8.111 said to perform in 64 bits...).

I am now looking forward to see the results...

Cheers,

Thomas
