Hi, I am trying to run findIsotopes from package CAMERA.

The following error, I believe related to igraph is produced (sessionInfo follows). Is there a fix for this, or am I doing something wrong here. The error repeats with attached code, as well as when called on other data.  Thanks in advance.

Based the analysis of findIsotopes on another computer, and browsing the session info from the other helpful comments,  it was found that rolling back R to 3.1.1 and igraph to version 0.7.1 regains findIsotopes functionality. Note that my install of Bioconductor and CAMERA on another computer in 2014 automatically installed igraph to the previous, compatible version. Reinstalling R today to version 3.1.1 on the workstation where the error was produced, and then installing bioconductor and camera,  installs igraph v 1.0.1.  After this,the function findIsotopes() does not work (see first session below).
Downloading igraph 0.7.1 and then updating that package by zip file does work (see second session).   I did not test this igraph rollback on R.3.2.1, so it may work there.

Since it seems there is an underlying and greater root cause for the error, I will not post this as answered yet, but consider this a temporary workaround. There are other warnings in the load of camera based on mzR and Rcpp, so as a user, I may try to roll back Rcpp as well on my system.

Hi

I could also find a temporal solution with R 3.2.1. I use to keep previous packages installation when I update R, so l load previous igraph and CAMERA packages and I am able to perform findIsotopes().

library(xcms)
library(igraph, lib.loc = "/home/R/3.1")
library(CAMERA, lib.loc = "/home/R/3.1")

cdffiles <- file.path(dataDir,"cdf.mzXML")
msSet <- xcmsSet(files = cdffiles, method = "centWave", ppm = 15, peakwidth = c(5,12), snthresh = 10)

But this solution is tricky, you have to be sure you don't have two versions of the same package in the two library locations. For the moment I have created a .Renviron file (see help(Startup) for info) so I don't have to use this lib.loc option in all my scripts

I tried to reproduce with pretty much the exact same sessionInfo() (a different windows version was the only difference) and could not. I have asked the CAMERA maintainer to take a look at this thread.

I created a bugfix for this problem, which should properly imports the methods from igraph now. This is commited to the release and devel branch. They new version should be build tomorrow.

The problem is that the CAMERA package imports 'xcms::groups', as well as all symbols from the igraph package. The igraph package now defines a 'groups' S3 generic, and it is 'seen' from within CAMERA, as hinted by the warning about replacing previous imports. The solution (I think the CAMERA maintainer will address this) is to selectively import from 'igraph', or to explicitly invoke xcms::groups() in the CAMERA code. As a workaround, after loading CAMERA, one can re-define the 'groups' import to be xcms::groups, as

library(CAMERA)
imports = parent.env(getNamespace("CAMERA"))
unlockBinding("groups", imports)
imports[["groups"]] = xcms::groups
lockBinding("groups", imports)

Great! Thanks, Martin! That solves my problems!
