weights
Extract Model Weights

### Description

Extract weights value for fitted model.

### Usage

    weights(object, ...)
    ## Default S3 method:
    weights(object, ...)
    ## S3 method for class 'glm':
    weights(object, type = c("prior", "working"), ...)

### Arguments

object | An lm or glm object (the output of the lm() or glm() functions), or a list with a component named weights.
... | arguments to be passed to or from future methods. (These are not used by the default or lm methods.)
type | character object, specify type of returned weights, must be either "prior", the default, or "working". This is used only by the glm method: the default method returns the prior weights only (there are no "working" weights in least squares regression).

Value
vector of weights value of fitted model.

Examples

    library(Sdatasets)
    wlmfit <- lm(cost ~ age + type + car.age, data=Sdatasets::claims,
        weights=number, na.action=na.exclude)
    weights(wlmfit)
    glmfit <- glm(cbind(ncases, ncontrols) ~ agegp + C(tobgp, , 1) +
                  C(alcgp, , 1), data = Sdatasets::esoph, family = binomial)
    weights(glmfit)
    weights(glmfit, type="working")
