get_laglead: Construct or extract data that represents a lag-lead window

In pammtools: Piece-Wise Exponential Additive Mixed Modeling Tools for Survival Analysis

Construct or extract data that represents a lag-lead window

Description

Constructs lag-lead window data set from raw inputs or from data objects with suitable information stored in attributes, e.g., objects created by as_ped.

Usage

get_laglead(x, ...)

## Default S3 method:
get_laglead(x, tz, ll_fun, ...)

## S3 method for class 'data.frame'
get_laglead(x, ...)

Arguments

x	Either a numeric vector of follow-up cut points or a suitable object.
...	Further arguments passed to methods.
tz	A vector of exposure times
ll_fun	Function that specifies how the lag-lead matrix should be constructed. First argument is the follow up time second argument is the time of exposure.

Examples

get_laglead(0:10, tz=-5:5, ll_fun=function(t, tz) { t >= tz + 2 & t <= tz + 2 + 3})
gg_laglead(0:10, tz=-5:5, ll_fun=function(t, tz) { t >= tz + 2 & t <= tz + 2 + 3})
