Plotly: set_credentials_file("your user name" "your credentials) does not work

Dear Mike, apologies for your difficulty, I think the problem here is that I originally wrote that in 2015 and things moved on without me noticing. I imagine you have followed Maras good advice on following the latest documentation. I would add that the usethis package by Hadley Wickham and Jenny Bryan provides a way to store these kinds of values either in your R profile or environment file. This makes storing credentials for future use a lot easier and safer.

usethis::edit_r_profile()
usethis::edit_r_environ()

The help pages for usethis are good. Guess I will go back and fix that post. Best, Paul
