update_twitter_user: Update or get tweets from a Twitter wall

In jogrue/RfacebookHelperFunctions: Useful functions for Rfacebook and rtweet

Description

This function updates one Twitter user's wall with rtweet's get_timeline() function. It looks for a previously stored data.frame (readable by readRDS). If there is one, it tries to scrape newer and older tweets than the ones already stored in the data.frame. Otherwise it creats a new data.frame.

Usage

update_twitter_user(
  user,
  datafile,
  n = 100,
  token = NULL,
  max_repeats = 100,
  debug = FALSE
)

Arguments

user	A twitter user name or ID.
datafile	The full path to an RDS data file.
n	The number of tweets to scrape from the wall, defaults to 100.
token	Provide a token, defaults to NULL.
max_repeats	The number of repeated calls to scrape data backwards. If go_back is TRUE, there will be repeated calls to go back in time (each call gets the number of posts in n_posts). The backward scraping will stop after max_repeats is reached. Defaults to 100.
debug	Show more messages during the updating process, default is FALSE.

Value

TRUE if it ran through.
