On unified finite integral involving product of Psi-function of two variables and generalized R-function

In this paper, we evaluate a finite integral with the generalized R-function and incomplete Psi-functions of two variables. On account of the most general nature of the functions occurring in the integrand of the second integral, our findings provides interesting unifications and extensions of a number of new and known integrals. At the end of this study, we shall two particular cases.
