`dimnames(matrix2) <- dimnames(matrix1)` ? – Ronak Shah Jun 30 '20 at 09:03 — Ronak Shah, Jun 30 '20 at 09:03

You could transfer the column names using dimnames<-

dimnames(matrix2) <- dimnames(matrix1)

which does the job of

rownames(matrix2) <- rownames(matrix1)
colnames(matrix2) <- colnames(matrix1)
