How can I collect all questions with a specific tag?

I'm trying to use the Stack Exchange API to collect all questions under a specific tag using this code:

library(stackr)

df_r_questions <- stack_tags("python","questions", num_pages=1000000, pagesize=100)

However I receive this error:

Error in match.arg(special, c(special_ids, special_no_ids)) : 
  'arg' should be one of “faq”, “related”, “synonyms”, “wikis”, “info”, “moderator-only”, “required”

Any update I should make?

I think stack_tags returns information about the tags themselves, not questions with a particular tag. Perhaps you are looking for stack_questions?

library(stackr)
library(tidyverse)

stack_questions(from = '2022-12-21', todate = '2022-12-22', tagged = 'r') %>%
  select(title) %>%
  as_tibble()
#> # A tibble: 30 x 1
#>    title                                                                      
#>    <chr>
