r - QUANTEDA-无效的类“dfmSparse”对象

我收到此警告消息。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怎么了？

谢谢！

最佳答案

我通过安装矩阵库解决了问题，然后重新安装了Quanteda，最后我重新启动了R，现在dfm可以了。

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