"incomplete final line" in `registerOptions` in `qualtRics 2.0`

[rdrr1990]

I've used qualtRics 1.0 without issue (and really like the R API!). Yesterday, when setting up a co-worker's computer, I noticed 2.0 is out on CRAN. I adapted the code I had used for qualtRicsConfigFile and created the .qualtRics.yml file as instructed into a new plain text file with Notepad (Windows machine). Unfortunately, when I ran registerOptions it threw an error: incomplete final line. So, it found the file OK but presumably hit a harmless error on readLines. Fortunately I was able to download the data by reading through registerOptions and setting the relevant options and environment variables.

Sys.setenv(QUALTRICS_ROOT_URL = "https://someorganization.qualtrics.com")
Sys.setenv(QUALTRICS_API_KEY = "ASDFqwertyNOTanAPIkey")
options(QUALTRICS_VERBOSE = T, QUALTRICS_USELABELS = T,
        QUALTRICS_CONVERTSTANDARDCOLUMNS = T,
        QUALTRICS_USELOCALTIME = F)

Maybe it's just a notepad issue, not sure. Wanted to let you know. Wonder if it wouldn't be easier to generate the yml file for the user...

Hi Pete,

Thanks for your comment.

It's strange that R throws that error. Could you post a screenshot of the R console here?

On unix the readLines error you mention is a warning, and the file is still loaded. Is this also the case on Windows, or did you have to set your credentials manually?

You can resolve the error by adding an empty line to the end of the file (that's how readLines knows that it has reached the end of the file).

It's also possible to pass these parameters to the registerOptions() function. You don't need to set the environments and options manually.

I've thought about creating that file for the user and I might implement that in the next version. Thanks for the suggestion.

Best,

Jasper.

hey jasper,

The Windows machine with the problem is not my computer and unfortunately not sure when I'll next have access to it. Yesterday, I did try a couple versions of the yaml file (with and without an extra line break, with and without an extra line with ---) without luck. The error forced registerOptions to exit before it got to the settings. I had no option but to set the credentials manually with the above (which worked fine but may be a bit daunting for the typical survey analyst....).

I just installed qualtRics 2.0 on my mac and registerOptions works fine. I created the yaml file using RStudio and didn't hit the incomplete final line issue (which I think is just a warning on a Mac as well...).

Overall, the Windows machine wasn't mine and I didn't have any real time to troubleshoot so others may have better luck. But unless there's some reason not just to have registerOptions or qualtRicsConfigFile take care of the settings file, that might be the way to go...

HTH,

I'll have a look at the CRAN policies to see whether altering files on a user's machine is allowed. Thanks for notifying me of this!

I tried to reproduce this error on Windows 10 but everything went fine.
