[pstricks] Another question: \pspsplotImp

[Zbigniew Nitecki]

The following code
			\begin{pspicture}(-2,-2)(2,2)
				\psplotImp[linecolor=red, algebraic](-3,3)(-3,3){x+y}
			\end{pspicture}

(clearly, I am using a simple function just to test the macro)
yields the error message

What can I possibly be doing wrong?
