Hi Jack,

Thanks for your response.

Yes, I am using :session evaluation here, set using #+PROPERTY:

However, ":results value html" does not work for me. In fact, this produces=
 no
table output at all in the resulting exported html file.

The output sent to the R :session buffer is printed correctly (when using
either :results value html or :results output html). As you say, it is the
exporter that is removing ">" from the output.

If I remove :session evaluation, I also get no output at all from these cod=
e
blocks in the exported html.

The change has been introduced within the last 12 months, as my scripts
exported with correct html formatting when I used them for last years' clas=
ses.

Best regards,
Steve
