apc (version 2.0.0)

apc.data.list.subset: Cut age, period and cohort groups from data set.

Description

For a recursive analysis it is useful to be able to cut age, period and cohort groups from a data set. Function returns an apc.data.list with data.format "trapezoid".

When used with default values the function turns an apc.data.list into a new apc.data.list with data.format "trapezoid" without reducing dataset.

Usage

apc.data.list.subset(apc.data.list,
							age.cut.lower=0,age.cut.upper=0,
							per.cut.lower=0,per.cut.upper=0,
							coh.cut.lower=0,coh.cut.upper=0,
							apc.index=NULL,
							suppress.warning=FALSE)

Value

response

matrix (or vector). Numbers of responses.

dose

matrix (or NULL). Numbers of doses.

data.format

"trapezoid"

age1

Numeric.

per1

Numeric.

coh1

Numeric.

unit

Numeric.

per.zero

Numeric.

per.max

Numeric.

Arguments: Notes

If apc.index is supplied then the input can be simplified. It suffices to write apc.data.list = list(response=response,data.format=data.format,dose=dose), where dose could be dose=NULL. Likewise apc.index does not need to be a full apc.index list. It suffices to construct a list with entries age.max, per.max, coh.max, age1, per1, coh1, unit, per.zero, index.trap, index.data.

The below example uses artificial data. For an example using data.asbestos see apc.plot.fit.
