I would like an app that when I click a button, my profile picture is changed and a tweet is sent saying I am on strike for the day. Who want to help build this?

The tricky part to do it in R/shiny is pushing the image to the profile, as no rtweet function can do that (yet).

application created and sent to: https://colomb.shinyapps.io/activism-twitteravatar/

created thanks to some direction https://medium.com/@skyetetra/how-to-make-rtweet-r-shiny-apps-with-user-credentials-48acca246b58

NB: this is not yet a package:

-install magick and rtweet packages,

• download or copy the function.r file,
• run it and then do

newtwitteravatar(tweetname= "your twitter name")

it will create a new avatar for you to upload on twitter at images/newavatar.
