I get this warning-message. I use these data:

https://github.com/kbenoit/quanteda/tree/master/data/data_char_inaugural.RData

RStudio version: Version 1.0.136 – © 2009-2016 RStudio, Inc.

 library(quanteda)
 uk2010immigCorpus <- corpus(data_char_ukimmig2010, docvars = data.frame(party = names(data_char_ukimmig2010)),metacorpus = list(notes = "Immigration-related sections of 2010 UK party manifestos"))
 mydfm <- dfm(uk2010immigCorpus, remove = c("will", stopwords("english")),removePunct = TRUE)


 Error in validObject(.Object) : invalid class “dfmSparse” object: superclass "replValueSp" not defined in the environment of the object's class

What's wrong with QUANTEDA?

Thanks! majesus

Yes it seemed to be an issue with your version of the Matrix package. Always best to make sure your packages and R version are up to date. We need some of the newer functions in Matrix to make the sparse object handling work. - Ken Benoit
And in the future, this sort of qn is better for an issue on GitHub than SO. - Ken Benoit
Thanks for your kindness. Your response and advice have been helpful. In the future I will use the channel you suggest me, for my doubts about Quanteda. - majesus

I solved the problem by installing Matrix library and then reinstalling quanteda, finally I reboot R and now dfm works.

install.packages("Matrix")
install.packages("quanteda")
