Get StackOverflow Questions For A List of Tags

Extract StackOverflow questions for a given set of tags, exluding questions related to an optional list of tags. This code is based on the tidyverse tweets bot by Jake Thompson.

get_stack_questions(extracted_tags = NULL, excluded_tags = NULL,
  time_window = 60, add_process_fn = NULL, ...)

Arguments

extracted_tags	A character vector of tags to extract questions for.
excluded_tags	A character vector of tags to exclude questions from the output.
time_window	Numeric, the timewindow to extract questions for (in minutes. Defaults to 60 minutes. Note that a maximum of 100 questions are extracted by the StackOverflow api, if you expect your tags to have a high volume of questions reduce this. If using this function as part of a sheduled bot makes sure this time frame corresponds the frequency with which your bot is running.
add_process_fn	A function. If additional munging or data extraction is required add to a custom function and pass here. This function must except a dataframe as its first arguement and return a dataframe. See the examples for details.
...	Pass additional arguements to stackr::stack_questions.

Value

A list containing the title, creation date, link, and tags for StackOverflow questions related to your selected tags.
