Hi,
right, one needs \usepackage{bidi}, then this kind of works:
\setRTL
\begin{choicegroup}[flip]{\LRE{Which software do you prefere for
the following tasks?}}
% We have to add the possible choices at the start.
\groupaddchoice{\LRE{\LaTeX}}
\groupaddchoice{\LRE{LibreOffice}}
\groupaddchoice{\LRE{Microsoft Word}}
\groupaddchoice{\LRE{other}}
% After that it is possible to add each question.
\choiceline{\LRE{writing letters}}
\choiceline{\LRE{creating tables}}
\choiceline{\LRE{typesetting equations}}
\end{choicegroup}
\unsetRTL
The question is on the wrong side, but one can suppress it (empty
string) and typeset it manually, I suppose.
The \LRE for the header is not needed (i.e. the cells that end up being
the column header, not sure why). That seems like a bug somewhere.
