[R] intersection of two matrices(updated)

Hi, I have two matrices as follow: matrix A = a=matrix(c(c("abc","abc","bcd","bcd","bce","bce"),c("a1","d2","d1","d2","a1","a2")),6,2) and matrix B which contains pair of values : b=matrix(c(c("a1","a1"),c("a2","d2")),2,2) In short, I wish to find out pairs of values in matrix a[,2] having s

[R] intersection of two matrices

Hi, I have two matrices as follow: matrix A = a=matrix(c(c("abc","abc","bcd","bcd","bce","bce"),c("a1","d2","d1","d2","a1","a2")),6,2) and matrix B which contains pair of values : b=matrix(c(c("a1","a2"),c("a1","d2")),2,2) In short, I wish to find out pairs of values in matrix a[,2] having sam
