Error: No tidy method for objects of class LDA_VEM§
Error: No tidy method for objects of class LDA_VEM§
我严格按照 "Text Mining in R: a Tidy Approach" 书第 6 章中介绍的步骤进行操作。参见:https://www.tidytextmining.com/topicmodeling.html
#import libraries
library(topicmodels)
library(tidytext)
#access dataset
data("AssociatedPress")
# set a seed so that the output of the model is predictable
ap_lda <- LDA(AssociatedPress, k = 2, control = list(seed = 1234))
#tidy model object
ap_topics <- tidy(ap_lda, matrix = "beta")
在终端中给我以下错误:
Error: No tidy method for objects of class LDA_VEM
同时我应该得到的是:
## # A tibble: 20,946 x 3
## topic term beta
## <int> <chr> <dbl>
## 1 1 aaron 1.69e-12
## 2 2 aaron 3.90e- 5
## 3 1 abandon 2.65e- 5

## 9 1 abbott 2.13e- 6
## 10 2 abbott 2.97e- 5

为什么我看到的是这个错误,而不是我想要的结果?
您需要先整理一下美联社的数据。像这样:
#if(!require("topicmodels")) install.packages("topicmodels")
#install.packages("topicmodels")
library(topicmodels)
data("AssociatedPress",package="topicmodels")
AssociatedPress
#Getting the Terms
terms<-Terms(AssociatedPress)
head(terms)
#tidyig with the tidy function
ap_tidy<-tidy(AssociatedPress)
然后:
ap_lda<-LDA(AssociatedPress,k=2,control=list(seed=1234))
ap_topics<-tidy(ap_lda,matrix="beta")
head(ap_topics)
给出:
topic term beta
<int> <chr> <dbl>
1 1 aaron 1.69e-12
2 2 aaron 3.90e- 5
3 1 abandon 2.65e- 5
4 2 abandon 3.99e- 5
5 1 abandoned 1.39e- 4
6 2 abandoned 5.88e- 5
您不是第一个 运行 遇到此问题的人,但很难重现。事实上,我个人从未能够重现该错误。但是,我知道这是一个真正的问题,因为,好吧...如果您希望看到其他人也在苦苦挣扎,请查看 here or here or here or here。
据我所知,这可能是 topicmodels 包中与 S4 注册相关的错误。您可以通过在会话和 always starting from a fresh R session when you open up work.
之间不保存 .RData
来避免 运行ning 进入此状态
