! `ROI.id` must be size 0 or 1, not 2.

[Anthony Aylward]

Describe the bug
Cannot load XML with XML.to.ggPlantmap(). The following error occurs:

Error in `dplyr::mutate()`:
ℹ In argument: `ROI.id = seq(1, length(unique(final.ROI$id)))`.
Caused by error:
! `ROI.id` must be size 0 or 1, not 2.
Run `rlang::last_trace()` to see where the error occurred.
Warning message:
Unknown or uninitialised column: `id`. 

The backtrace from rlang::last_trace():

Any idea what might cause this?

To Reproduce
XML.to.ggPlantmap("filename")

Expected behavior
The XML file loads into a ggPlantmap

Hello,
Thank you for the issue report,
It seems that your XML file is missing the id column,
Would you mind sending me your .XML file to [e-mail]?
Also, would you mind sending me the version of ICY you used to generate the xml file?
Thanks!

[Anthony Aylward]

Thanks, it was indeed a problem with the specific XML file. I got things working with a different file and now the package is doing what I need, so I'll close the issue.
