如何将列表转换为R中的语料库？

Question

In this question I asked how to split a huge dataframe to create a corpus. Thanks to the answer I was able to create a list from a dataframe. My problem was still obtaining a corpus from the list I created in order to do some text mining and cluster the data according to the search term.

Answer 1

To solve this problem I just applied the as.VCorpus function of the tm package to the list I created before:

new_corpus <- as.VCorpus(new_list)

Check if the new object is a corpus:

class(new_corpus)
[1] "VCorpus" "Corpus" 

I thus created a "volatile corpus". As written in the R documentation:

A volatile corpus is fully kept in memory and thus all changes only affect the corresponding R object.
