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 !!##"ยค does this have to do with the subject line?
B: This should do it:
cbind(A[rep(1:217,length=16063),], B)
But note that makes 74 + 5/217 copies of A, and I did wonder if that was
the intention (or if not, what was intended).
