6 years ago I'm happy, you find the package useful!
It seems to me, you are trying to recreate the vignette "Analysing n-grams with jstor". From your error messages it appears to me, that you are using the source version on Github. This part
bigram_files <- readr::read_rds("bigram_paths.rds")is only executed locally by me, when I create the vignette, because it is faster than
bigram_files <- list.files(path = c("receipt-id-624621-part-001/ngram2/",
"receipt-id-624621-part-002/ngram2/"),
full.names = T)when I render the vignette a few times while working on it.
The "correct" vignette, combined with output, can be found here: https://ropensci.github.io/jstor/articles/analysing-n-grams.html#importing-bigrams
If you want to save the paths to disk in order to speed up the process for re-running, you might want to do it like this:
# list all files
bigram_files <- list.files(path = c("path_to_directory_with_bigrams/",
"another_path_to_directory_with_bigrams"),
full.names = T)
# write a single object with the list of paths to disk
readr::write_rds(bigram_files, "path_to_save_the_list_of_paths.rds")The next time you run your script, you can simply use
bigram_files <- readr::read_rds("path_to_save_the_list_of_paths.rds")to load the paths.
Depending on the number of files and the speed of your disk, this might save you some time.
FIrst, thank you for this jstor package. It seems perfectly fitted for working with the DfR files. I am having an issue though and thought I'd ask you about it. I'm very much a beginner but in following you example I get the following error when I try to access the bigrams_files:
I'm not sure what's happening here. I'm working in rStudio and it appears that the value is there:
Any help would be greatly appreciated and thank you again for putting together a very useful tool.
