求助topicmodels package

> docs11 <- Corpus(VectorSource(docs10))
> tdm <- TermDocumentMatrix(docs11)
> lda <- LDA(tdm, 30,method='Gibbs')
> Terms<-terms(lda,5)
> Terms[,1:5]

output是这样的
Topic 1 Topic 2 Topic 3 Topic 4 Topic 5
[1,] "7"     "6"     "2"     "4"     "1"   
[2,] "10"    "11"    "1"     "16"    "3"   
[3,] "14"    "19"    "9"     "17"    "4"   
[4,] "18"    "1"     "12"    "8"     "6"   
[5,] "20"    "2"     "3"     "20"    "2"   

为什么output是数字而不是term呢？
