I am text-mining a series of interviews I performed in the Slovene language. After I transformed the vector file into a corpus, I tried this command to stem the words:
pupils<- tm_map(pupils, stemDocument(pupils, language = "slovene"))
However, the response was this:
Error in UseMethod("stemDocument", x) : no applicable method for 'stemDocument' applied to an object of class "c('VCorpus', 'Corpus')"
I could perform the intended text mining operations (ngrams) without the stemming process, but they will not be completely legit. I saw the post where a gentleman asked about stemming in Italian and was instructed to use the SnowballC package. Unfortunately, SnowballC does not incorporate Slovene, so there's that.
I will appreciate any help. Thank you. Janez
