outfile:"png" specifies that you want png output saved to a file in
the org-attach dir for the current entry. However, I think that your
table is not in an entry (i.e. there is no heading in the file
above). So org-attach complains. I think in this case this is
appropriate behaviour, rather than a bug.

So, make sure that you are working in an org entry, by adding a
heading above the table, e.g.

[the following should now work.]

#+R: action:hist columns:1 colour:hotpink
#+R: intable:continuous-data outfile:"png" title:"histogram example"
