- object
the model object as returned by glm.

- conf.level
confidence level of the interval.

- sides
a character string specifying the side of the confidence
interval, must be one of `"two.sided"`

(default), `"left"`

or
`"right"`

. `"left"`

would be analogue to a hypothesis of
`"greater"`

in a `t.test`

. You can specify just the initial
letter.

- adjusted
logical, defining if the R squared or the adjusted R squared
should be used. Default is `TRUE`

, returning the latter.

- ...
further arguments are passed to the `boot`

function.
Supported arguments are `type`

(`"norm"`

, `"basic"`

,
`"stud"`

, `"perc"`

, `"bca"`

), `parallel`

and the number
of bootstrap replicates `R`

. If not defined those will be set to their
defaults, being `"basic"`

for `type`

, option
`"boot.parallel"`

(and if that is not set, `"no"`

) for
`parallel`

and `999`

for `R`

.
