Can someone please refer me to a function or method that resolves this structuring issue: I have two matrices with identical colnames (89), but varying number of observations: matrix A matrix B 217 x 89 16063 x 89 I want to creat one matrix C that has both matrices adjacent to one another, where matrix A is duplicated many times to create the same row number for matrix B, i.e. 16063. matrixA matrix B matrixA matrixA so matrix C will be 16063 x 178 I've tried cbind() and merge() with no success..
A: What the !!##"?? does this have to do with the subject line? B: This should do it: cbind(A[rep(1:217,length=16063),], B)
