问题描述

直接从使用R进行文本挖掘中运行此脚本,

  library(topicmodels)
库(扫帚)

data( AssociatedPress)
ap_lda<-LDA(AssociatedPress,k = 2,控件=列表(种子= 1234))
整洁(ap_lda)

我收到此错误消息:



  packageVersion( topicmodels)





  sessionInfo()

解决方案

tidytext 软件包似乎正在扩展扫帚中使用的某些方法。包...



因此,请使用 tidytext tidy 函数c>确实起作用:

  b帚:: tidy(ap_lda,matrix = beta)

as.data.frame.default(x)中的错误:
无法将类 structure( LDA_VEM,package = topicmodels)强制转换为data.frame
另外:警告消息:
在tidy.default(ap_lda,matrix = beta)中:
没有使用as.data.frame

tidytext :: tidy来整理LDA_VEM类的S3对象的方法。 (ap_lda,矩阵= beta)

当我加载 tidytext 时: library(tidytext) ,则无需指定.ie即可自动为我工作 tidy(ap_lda,...)。我从您的会话信息中看到, tidytext 未加载。


Running this script, straight from 'Text mining with R',

library(topicmodels)
library(broom)

data("AssociatedPress")
ap_lda <- LDA(AssociatedPress, k = 2, control = list(seed = 1234))

I get this error message:

解决方案

The tidytextpackage appears to be extending some of the methods used in the broom package...

So using the tidy function from tidytext does work:

broom::tidy(ap_lda, matrix = "beta")

Error in as.data.frame.default(x) : 
  cannot coerce class "structure("LDA_VEM", package = "topicmodels")" to a data.frame
In addition: Warning message:
In tidy.default(ap_lda, matrix = "beta") :
  No method for tidying an S3 object of class LDA_VEM , using as.data.frame

tidytext::tidy(ap_lda, matrix = "beta")

# A tibble: 20,946 x 3
   topic term                                        beta

# ... with 20,936 more rows

When I have loaded tidytext : library(tidytext) then this works automatically for me without specifying .i.e. tidy(ap_lda, ...). I can see from your session info that tidytext is not loaded.
