LT1-class {eoR}

LT1 class for HMD life-tables 1x1

Description

The class LT1 stores HMD life table information in a systematic way.

The header-method gets the raw header information of an LT1 object

The lt1-method gets the life table information of an LT1 object

The content-method gets the life table information of an LT1 object

The region-method gets the regional information of an LT1 object

The protocol-method gets the protocol information of an LT1 object

The LTable1-constructor creates an LT1 object

The length-method gets the number of rows int the LT1 lt1 data.table

The selectYears-method gets a subset of an LT1 object

The readLT1x1-method reads all information from the file 1x1 period life table

Details

This LT1 class fits to Human Mortality Database (HMD) 1x1 period life tables. See https://www.mortality.org/ for data details. An LT1 instance stores the raw header, the content, the version protocol and regional information and the life table as a data.table object. The validation adds a pure numeric age AgeLow to the life table. Try demo(LT1) for a demonstration.

Value

The header-method returns the raw header information

The lt1-method returns the life-table

The protocol-method returns the protocol information

The LTable1-constructor returns an LT1 object

The length-method returns the number of rows

The selectYears-method returns an LT1 object

The readLT1x1-method returns an LT1 object
