Dear BioC, answering to a recent query on the mailing list I noticed a small typo in the example provided in the AnnotatedDataFrame help page: AnnotatedDataFrame(data=df, varMetaData=metaData) should be AnnotatedDataFrame(data=df, varMetadata=metaData) also, no error is given when calling directly AnnotatedDataFrame (the varMetadata slot is empty) but calling new('AnnotatedDataFrame') produces an error where 'varMetaData' is not a valid slot name. Best. J.

I think what you mean is that AnnotatedDataFrame(varMetaData=data.frame()) doesn't result in an error. but should. These are both fixed in the devel branch, Biobase 2.15.4. Thanks!
