Dear R Developers, I hope this email finds you well.
As a newcomer to the world of R, I'm trying different exercises. In my way, I faced with some, seemingly, trivial problems but there is not any response for that around the web. So, I thought can get help from you. Specifically, in tutorial presented at http://www.rdatamining.com/doc s/twitter-analysis-with-r, I faced with a problem on using OAuth. When I use the first approach, the following error will be occurred: [1] "Using browser based authentication" Error in curl::curl_fetch_memory(url, handle = handle) : Failed to connect to api.twitter.com port 443: Connection refused And when it comes to the second approach, the following error rises: [1] "Using direct authentication" Error in check_twitter_oauth() : OAuth authentication error: This most likely means that you have incorrectly called setup_twitter_oauth()' Unfortunately, the online resources could not help. For example, all the solutions introduced in StackOverflow could not work for me. https://stackoverflow.com/questions/31128492/twitter-setup-t witter-oauth-failing *Moreover, in reading data from the current directory, the readRDS method sucks*. I got same error using import() in rio package. https://stackoverflow.com/questions/49908803/error-in-reading-files-in-r So, please let me know if you have some solution for the issues. Thanks for your consideration.
