Assuming you are dealing with vectors of numbers, you can form a "row" of data using the append function to stick b onto the end of a: > append( a, b ) [1] 9 7 8 8 4 5 This can be dumped to a file using write.table: write.table( t( append(a,b) ), 'test.txt', row.names=F, col.names=F, append=T ) The transpose function t() is used because write.table() assumes a singleton vector is a column vector and you want row vectors. If you have two matrices instead of vectors, say: matA <- matrix( rep(a,4), nrow=4, byrow=T ) matB <- matrix( rep(b,4), nrow=4, byrow=T ) Then you would use the cbind() function instead of the append() function to form your rows and drop the transpose function: write.table( cbind(a,b), 'test.txt', row.names=F, col.names=F, append=T ) If you want to overwrite (i.e. start a new file) when you use write.table, then drop the append=T.
