The electrical resistivity rho of RBa/sub 2/Cu/sub 3/O/sub 7-//sub y/, where R = La, Pr, Nd, Eu, Dy, Ho, Er, Sm, and Tm has been measured from room temperature up to 900 K. No essential difference in the transport properties was found except for LaBa/sub 2/Cu/sub 3/O/sub 7-//sub y/ and PrBa/sub 2/Cu/sub 3/O/sub 7-//sub y/ which shows an anomaly in the electrical resistivity. SmBa/sub 2/Cu/sub 3/O/sub 7-//sub y/ samples with various oxygen contents are studied in detail. Metallic behavior and linear temperature dependence of rho have been found for SmBa/sub 2/Cu/sub 3/O/sub 7-//sub y/ with 0
