I am hoping for advice regarding selecting two or more non-contiguous files to form a sub-corpus. This code selects 1 file: testcorpus <- texts (txtdata)[2]



If I wanted to form a corpus combining files 1 and 25, how would I do this:



I tried to modify code I found on the net, with the following results:



> my_corpus1 <- corpus(txtdata)[1] 
> my_corpus2 <- corpus(txtdata)[25]
> my_corpus3 <- ( my_corpus1 + my_corpus2)
Error in my_corpus1 + my_corpus2 :
non-numeric argument to binary operator

> xx <- corpus(txtdata)[1] + corpus(txtdata)[25]
Error in corpus(txtdata)[1] + corpus(txtdata)[25] :
non-numeric argument to binary operator

> my_corpus3 <-c( my_corpus1 + my_corpus2)
Error in my_corpus1 + my_corpus2 :
non-numeric argument to binary operator


Any advice is appreciated,



Bob

          I'd do it this way:





          library("quanteda")
          ## Package version: 1.4.1
          ## Parallel computing: 2 of 12 threads used.
          ## See https://quanteda.io for tutorials and examples.

          corpus_subset(
          data_corpus_inaugural,
          seq_len(ndoc(data_corpus_inaugural)) %in% c(1, 25)
          )
          ## Corpus consisting of 2 documents and 3 docvars.


          The subset argument here is returning a logical vector where the first and 25th elements are true and the rest false, which selects those documents into your subcorpus.
