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