R: Create a matrix

modMATRIX {mrgsolve} | R Documentation

## Create a matrix

### Description

Create a matrix

### Usage

    modMATRIX(
      x,
      use = TRUE,
      block = FALSE,
      correlation = FALSE,
      digits = -1,
      context = "matlist",
      ...
    )

### Arguments

`x` | data for building the matrix. Data in `x` are assumed to be on-diagonal elements if `block` is `FALSE` and lower-triangular elements if `block` is `TRUE`
`use` | logical; if FALSE, all matrix elements are set to 0
`block` | logical; if TRUE, try to make a block matrix; diagonal otherwise
`correlation` | logical; if TRUE, off diagonal elements are assumed to be correlations and converted to covariances; if correlation is TRUE, then block is set to TRUE
`digits` | if value of this argument is greater than zero, the matrix is passed to signif (along with digits) prior to returning
`context` | the working context
`...` | passed along

### Examples

    modMATRIX("1 2.2 333")
    modMATRIX("1 1.1 2.2", block=TRUE)
    modMATRIX("23 234 234 5234", use=FALSE)

    ans <- modMATRIX("1.1 0.657 2.2", correlation=TRUE, block=TRUE)
    ans
    cov2cor(ans)
