bind matrices by row
...o bind them together by column using a loop (i.e. not writing cbind(matrix1, matrix2,matrix3....)). The reason is because in my real data set I have a very large number of matrices. Example: matrix1 <- matrix (1:12,4,3) matrix2 <- matrix (13:24,4,3) matrix3 <- matrix (25:36,4,3) matrix4 <- matrix (37:48,4,3) matrix5 <- matrix (49:60,4,3) for (i in 1:5) { allmatrix <- cbind(matrix1, get(paste('matrix', i, sep=""))) } However my command recycled the result and binds only the first and last matrices. Thanks always for your help Lorenz...
