Dear list, I have a problem when I try to use the IlluminaHumanMethylation27k.db (in marticular the method IlluminaHumanMethylation27kCHR) package from a package I am writing. In a previous post I asked how to integrate the information about the chromosomes in a MethyLumiM object. Tim (thanks for your help) suggested me this solution: /fData(AML)$chrom<- as.factor(unlist(mget(featureNames(AML), IlluminaHumanMethylation27kCHR)))/ It works perfectly if I use it from command line. But when I launch the same command from my package I have the following error: */Error in mget(featureNames(lumiMethy), IlluminaHumanMethylation27kCHR) : second argument must be an environment/* / /Inside the namespace of my package, I import the entire package IlluminaHumanMethylation27k.db. To solve the problem, I have already tried to use "as.environment()" and to require() the IlluminaHumanMethylation27k.db package inside mine. I tried also to use the function "getAnnMap" specifying as type "env". Nothing worked. Any new suggestion is welcomed!!! Many thanks!

Thanks to Martin Morgan and Tim Triche I solved the problem. The mget generic function is defined in AnnotationDbi. Simply, I was not importing this function into my package getting base::mget, which doesn't know anything about the AnnotationDbi packages. So adding in the DESCRIPTION file * Imports: AnnotationDbi* and in the NAMESPACE file * importMethodsFrom(AnnotationDbi, mget)* the package works fine.
