Create a Vector into MxMatrix-class
It converts a vector into MxMatrix-class via mxMatrix.
create.mxMatrix(x, type=c("Full","Symm","Diag","Stand"), ncol=NA,
nrow=NA, as.mxMatrix=TRUE, byrow=FALSE, ...)x |
A character or numeric vector |
type |
Matrix type similar to those listed in
|
ncol |
The number of columns. It is necessary when
|
nrow |
The number of rows. It is necessary when
|
as.mxMatrix |
Logical. If it is |
byrow |
Logical. If |

If there are non-numeric values in x, they are treated
as the labels of the free parameters. If an "*" is
present, the numeric value on the left-hand side will be treated as
the starting value for a free parameter or a fixed value for a fixed parameter. If it is a matrix of numeric values, there are
no free parameters in the output matrix. nrow and ncol
will be calculated from the length of x unless
type="Full" is specified.
A MxMatrix-class object with the same
dimensions as x
