Using API to load more than one question ids per call

Question

Using a dataframe with question ids from SO:

df <- data.frame (qid = c(71663375, 71674701, 71724524))

Using the folliwng code it is possible to make 3 api calls to receive info for every question.

However SO app provides the chance to run into 1 call 100 ids. How is it possible to make it?

library(stackr)
for (j in 1:nrow(df)) {
  
  questions <- stack_questions(df$qid[j])
}

Answer 1

If the app can handles 100 at a time, split the qid into list of vectors with each list element holding 100 at a time,

lst1 <- split(df$qid, as.integer(gl(nrow(df), 100, nrow(df))))

and then use lapply

library(stackr)
out <- lapply(lst1, stack_questions)
out_dat <- do.call(rbind, out)

or for loop to loop over the list

out <- vector('list', length(lst1))
for(i in seq_along(lst1)) {
   out[[i]] <- stack_questions(lst1[[i]])
}
out_dat <- do.call(rbind, out)

-output

> out
[[1]]
