\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{pstricks-add}

\begin{document}
\psset{dotscale=2}
\begin{pspicture}[showgrid=true](5,5)
\pnode(1,1){P}
\psdot(P) \pnode(!\psGetNodeCenter{P} P.x 4 add P.y 2 add){P'}
\psline{->}(P)(P')
\rput(5,5){\psdot[dotstyle=x](-3,-1)}
\rput(5,5){\psdot[dotstyle=o](! 180 cos 270 sin)}
\rput(2,2){\psdot[dotstyle=triangle](!90 cos 90 cos)}
\end{pspicture}

\end{document}
