vconcat(a,b,c,... [,labels:structure(rowLabs,colLabs), silent:T]) where a, b, c, ... matrices and rowLabs and colLabs are CHARACTER scalars or vectors |

vconcat(a,b,c,...) combines matrices a, b, c ... vertically by concatenating their columns. All arguments must be of the same type, REAL, LOGICAL, or CHARACTER, and have the same number of columns n. The result is a matrix of that type with n columns and ma+mb+mc+... rows, where ma, mb, mc, ... are the number of rows of a, b, c, ... . vconcat(a,b,...,labels:structure(rowLabs,colLabs) [,silent:T]) uses CHARACTER scalars or vectors rowLabs and colLabs as row and column labels for the result. With silent:T, no warning is printed if labels are the wrong size. See topic 'labels' for details. Any argument that is a vector of length m is considered to be a m by 1 matrix. In particular, if a is a vector of length m, vconcat(a) is a m by 1 matrix. An argument that is an array with only two dimensions not equal to 1 is considered to be a matrix (see 'matrices'). For example, vconcat(array(run(6),1,3,2),array(run(7,14),4,1,2)) is equivalent to vconcat(matrix(run(6),3),matrix(run(7,14),4)) Any argument of type NULL is ignored. When all arguments are NULL, so is the result. See also topics hconcat(), 'matrices', 'vectors'.
