各位大神帮忙看看怎么解决
用Rwordseg包做中文分词，报错代码如下：
wordsegment<- function(x) {
segmentCN(x)
}sample.words <- lapply(as.character(warningSet[,9]), removeNumbers)
##此时sample.words为list
sample.words <- lapply(sample.words, wordsegment)##其中sample.words是list
报错：
Error in .jcall(analyzer, "S", strfunc, X) : RcallMethod: attempt to call a method of a NULL object.
