Unable to set credentials, 'No such file or directory'

[arnoud999]

When I try to set my credentials/API key, I get the following error message:

[1] "Your credentials file:"
Error in if (file.info(CREDENTIALS_FILE)$size) { : 
  argument is not interpretable as logical
In addition: Warning message:
In file.create(abspath) :
  cannot create file '//studfiles.campus.uvt.nl/files/home/home09/u1236118/.plotly/.credentials', reason 'No such file or directory'

I've tried creating the .plotly folder and the .credentials file myself, and I tried running R through a command window as administrator, but in both cases I still saw the same error message.

@arnoud999 , are you on a personal computer? The credentials file tries to get created in ~/.plotly/. That error seems to be saying ~/.plotly doesn't exist. As a test, can you open up a terminal and do the following?

cd ~/.plotly

You've probably got a permissions problem, but I'm sure we can figure out a way to get you up and running.

The simplest thing to get going straight-away is to just sign in.

py <- plotly("your_username", "your_api_key")

In general, this isn't a great solution as you'll be hard-coding your credentials and you'd have to do it for every script.

Thanks for your quick response!

cd ~/.plotly (or cd ~\.plotly) doesn't work, probably because I'm running Windows?

py <- plotly("your_username", "your_api_key") gives me the same error as above.

It indeed seems to be a permission problem, I'm on a work computer and my user folder is some kind of network drive. Is it possible to change the location of .plotly?

[theengineear]

@arnoud999 , specifying the location of the .plotly folder could be nice, I think that would be pretty easy through an environment variable. We won't have this solution for you immediately, but I could definitely see the utility in this, so I'll see what I can do.

Until then, yes, you'll need to sort out the permission block. I had thought that our R library handled this though, @mkcor , thoughts?

@theengineear You are right, I remember troubleshooting Windows users in the past... But this may be yet another thing... It could be a thing to let users specify/overwrite environment variable PLOTLY_DIR...

I think Windows does not understand ~ (which is why our R code needs the path.expand("~") by the way). @arnoud999 It looks like your 'home' is not quite the home the way we usually assume -- you are on a workstation, I understand.

Can you try and run, say:

py <- plotly("rAPI", "yu680v5eii")

Please?

[arnoud999]

Unfortunately, I get the same error:

> py <- plotly("rAPI", "yu680v5eii")
Error in if (file.info(CONFIG_FILE)$size) { : 
  argument is not interpretable as logical
In addition: Warning message:
In file.create(abspath) :
  cannot create file '//studfiles.campus.uvt.nl/files/home/home09/u1236118/.plotly/.config', reason 'No such file or directory'

[mkcor]

@arnoud999 It's not the same error! The CREDENTIALS info is in but you are missing the CONFIG info, so please try this workaround:

py <- plotly(username="rAPI", key="yu680v5eii", base_url="https://plot.ly")

Let me know how it goes!

[arnoud999]

That works, thanks a lot! 👍
