Abstract
To determine entirely the resulting functions of one-loop integrals it is necessary to find the correct analytic continuation to all relevan t kinematical regions. We argue that this continuation procedure may b e performed in a general and mathematical accurate way by using the R- function notation of these integrals. The two- and three-point cases a re discussed explicitly in this manner.
