Retrieve and summarize abstracts from the current issue of a selected Nature Portfolio journal using a local LLM and save the output as CSV and/or HTML. Optionally filter the articles by a set of whitelist terms.
Arguments
- journal
A character string indicating the name of the supported Nature journal (e.g., "Nature Biotechnology").
- filename
A character string specifying the base filename for saving the report. Default is "natchat_summary".
- outdir
A character string specifying the directory to save output files. Default is current working directory ".".
- model
A character string specifying the local Ollama model to use for summarization (e.g., "llama3:instruct").
- save_csv
Logical. Save the results as a CSV file? Default is TRUE.
- save_html
Logical. Save the results as an HTML file? Default is TRUE.
- verbose
Logical. Should informative messages be printed to the console? Default is TRUE.

Details
This function is a convenience wrapper around get_articles(), add_prompt(), add_summary(), and save_report().
It scrapes the current issue, optionally filters articles using a whitelist of terms, summarizes abstracts using a local LLM, and exports the result.
Examples
if (FALSE) { # \dontrun{
summarize_journal(
journal = "Nature Medicine",
model = "llama3",
whitelist = c("CRISPR", "gene therapy"),
save_csv = TRUE,
save_html = TRUE
)
} # }
