ds.mxMatrix(type = "Full", nrow = NA, ncol = NA, free = FALSE,
  values = NA, labels = NA, lbound = NA, ubound = NA, byrow = FALSE,
  dimnames = NA, name = NA, newobj = "new_mxMatrix", datasources = NULL)

`type`	a character string indicating the matrix type, where type indicates the range of values and #' equalities in the matrix. Must be one of: 'Diag', 'Full', 'Iden', 'Lower', 'Sdiag', 'Stand', 'Symm', 'Unit', or 'Zero'.
`nrow`	the desired number of rows. One or both of 'nrow' and 'ncol' is required when 'values', 'free', 'labels', 'lbound', and 'ubound' arguments are not matrices, depending on the matrix type.
`ncol`	the desired number of columns. One or both of 'nrow' and 'ncol' is required when 'values', 'free', 'labels', 'lbound', and 'ubound' arguments are not matrices, depending on the matrix type.
`free`	a vector or matrix of logicals for free parameter specification. A single 'TRUE' or 'FALSE' will set all allowable variables to free or fixed, respectively.
`values`	a vector or matrix of numeric starting values. By default, all values are set to zero.
`labels`	a vector or matrix of characters for variable label specification.
`lbound`	a vector or matrix of numeric lower bounds. Default bounds are specified with an NA.
`ubound`	a vector or matrix of numeric upper bounds. Default bounds are specified with an NA.
`byrow`	logical. If 'FALSE' (default), the 'values', 'free', 'labels', 'lbound', and 'ubound' matrices are populated by column rather than by row.
`dimnames`	list. The dimnames attribute for the matrix: a list of length 2 giving the row and column names respectively. An empty list is treated as NULL, and a list of length one as row names. The list can be named, and the list names will be used as names for the dimensions.
`name`	an optional character string indicating the name of the MxMatrix object
`newobj`	the name of the new object. By default the name of the new object is "new_mxMatrix".
`datasources`	a list of opal object(s) obtained after login in to opal servers; these objects hold also the data assign to R, as `dataframe`, from opal datasources. By default an internal function looks for 'opal' objects in the environment and sets this parameter.

See details of the OpenMx function 'mxMatrix' in the package OpenMx.

a new mxMatrix object, which consists of a 'values' matrix of numeric starting values, a 'free' matrix describing free parameter specification, a 'labels' matrix of labels for the variable names, and 'lbound' and 'ubound' matrices of the lower and upper parameter bounds.
