QUANTEDA - 无效的类"dfmSparse"对象

Question

我收到了这条警告信息.我使用这些数据:

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

RStudio版本:版本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

QUANTEDA有什么问题？

谢谢!majesus

Answer 1

我通过安装Matrix库然后重新安装quanteda解决了这个问题,最后我重新启动了R,现在dfm正常工作.

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