    coef(object, ...)
      ## S3 replacement method for class 'optimx'
    coef(x) <- value

### Arguments

`object` | Object returned by `optimx`.
`...` | Further arguments to be passed to the function. Currently not used.
`x` | An `optimx` object.
`value` | Set parameters equal to this value.

### Value

`coef.optimx` returns the best parameters found by each method that returned such parameters. The returned coefficients are in the form of a matrix with the rows named by the relevant methods and the columns named according to parameter names provided by the user in the vector of starting values, or else by "p1", "p2", ..., if names are not provided.

### Examples

    ans <- optimx(fn = function(x) sum(x*x), par = 1:2)
    coef(ans)

    ## Not run:
    proj <- function(x) x/sum(x)
    f <- function(x) -prod(proj(x))
    ans <- optimx(1:2, f)
    ans
    coef(ans) <- apply(coef(ans), 1, proj)
    ans
