[R-pkg-devel] invalid DOIs

[Jan Wijffels]

Hello everyone,

I'm updating the R package image.textlinedetector which is already on CRAN.
When doing R CMD check on winbuilder. I receive the note:

Found the following (possibly) invalid DOIs:
  DOI: 10.1117/12.704538
    From: DESCRIPTION
    Status: Internal Server Error
    Message: 500

The relevant part in the DESCRIPTION file which caused this note looks like this:
... by Arivazhagan M. et al (2007) <doi:10.1117/12.704538>, and a wrapper for an image segmentation ...

This DOI hasn't changed and CRAN seems to parse it fine as the link is shown at the DESCRIPTION of the web page of the package at https://cran.r-project.org/package=image.textlinedetector
How to solve this? What is the correct doi to put in here?

many thanks for your help,
Jan
