Error: rampIsFile not found

Hi,

Today I suddenly started getting the following error when trying to read files:
Code: [Select]
Error in get(name, envir = asNamespace(pkg), inherits = FALSE) : 
  object 'rampIsFile' not found
This happens both when I try to read a file through xcmsRaw and through xcmsSet.

I can't directly pinpoint the reason why this error started popping up, so I'll try to give a complete overview of the things I did before it happened. First I installed the R package 'metabolomics' (http://http://cran.r-project.org/web/packages/metabolomics/index.html). I used this package to (try to) create a dendrogram, however, when I came back from lunch, I saw that this caused my computer to run out of RAM (I probably made a mistake somewhere, but I didn't really check what I did wrong), which caused me to force reboot my computer. Then after this reboot the error manifested.

To try to solve the problem I tried to return to the previous working configuration, so I uninstalled metabolomics and reinstalled Rcpp, mzR and xcms. However, the error keeps popping up.

How can I solve this and get xcms running again?

I reinstalled R and then installed all my packages from scratch, and that has solved the problem.

Although I'm still interested what went wrong, because I'd still like to use the 'metabolomics' package, although I didn't dare to install it at the moment.
