Log-Likelihood of a gnls Object

Returns the log-likelihood value of the nonlinear model represented by object evaluated at the estimated coefficients.

## S3 method for class 'gnls'
logLik(object, REML, ...)

`object`	an object inheriting from class `"gnls"`, representing a generalized nonlinear least squares fitted model.
`REML`	an logical value for consistency with `logLik,gls`, but only `FALSE` is accepted..
`...`	some methods for this generic require additional arguments. None are used in this method.

the log-likelihood of the linear model represented by object evaluated at the estimated coefficients.
