Description

Summarize an "opm" object.

Usage

# S3 method for opm
coef(object, ...) 
  # S3 method for opm
coef(x) <- value

Arguments

object

Object returned by opm.

…

Further arguments to be passed to the function. Currently not used.

x

An opm object.

value

Set parameters equal to this value.

Value

coef.opm 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

# NOT RUN {
ans <- opm(fn = function(x) sum(x*x), par = 1:2, method="ALL", control=list(trace=0))
print(coef(ans))

ansx <- optimx(fn = function(x) sum(x*x), par = 1:2, control=list(all.methods=TRUE, trace=0))
print(coef(ansx))


# }
# NOT RUN {
proj <- function(x) x/sum(x)
f <- function(x) -prod(proj(x))
ans <- opm(1:2, f)
print(ans)
coef(ans) <- apply(coef(ans), 1, proj)
print(ans)
# }
# NOT RUN {
