HI all: I have a customized source reader for the package tm (that Milan Bouchet-Vallat has been instrumental in producing). I can get it to produce a corpus of class: "VCorpus" "Corpus" "list"
class(mycorp[1]) returns "VCorpus" "Corpus" "list" and class(mycorp[[1]] returns "PlainTextDocument" "TextDocument" "character" But now that I've got a corpsu, none of the transformation functions work at all. They all return the following error (with the respective function name) Error in UseMethod("stripWhitespace", x) : no applicable method for 'stripWhitespace' applied to an object of class "NULL" I haven't seen this error reported anywhere in the R-list archives. Does anyone have any suggestions? Yours, Simon Kiss P.S.
