Technical information about this website’s accessibility

Maths Research IT Support is committed to making its website accessible in accordance with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.

This website is partially compliant with the Web Content Accessibility Guidelines version 2.1 AA standard, due to the known issues listed below.

Non accessible content

The content that is not accessible, where it fails the success criteria, will be made accessible within 3 calendar months of the date on which this statement is published.
Some documents and content are exempt from the regulations (such as live video content and PDFs or other documents published before 23 September 2018 if they’re not essential to providing our services), so we do not currently have any plans to make them accessible.

Non compliance with the accessibility regulations

  • Colour contrast issues
  • Content in inaccessible documents such as old PDFs
  • Content is not optimised to display on different screen sizes or orientation

These issues fail a WCAG 2.1 success criterion.

Disproportionate burden

This site is an exact mirror of an externally-hosted site whose content we have no control over. Web content and software is contributed to this site from users and developers of the R Statistical Mathematics programming language worldwide with frequent updates daily. It is not possible to check and update remote content which we simply mirror and do not create.

Reporting accessibility issues

If you need information on this website in a different format like accessible PDF, large print, easy read, audio recording or braille or if you find any accessibility issues not listed on this page then please contact We will consider your request and get back to you within 48 hours.
