modify_item: Modify the value of existing items

In Roche/descem: Discrete Event Simulation for Cost-Effectiveness Modelling

Modify the value of existing items

Description

Modify the value of existing items

Usage

modify_item(list_item, env_ch = NULL)

Arguments

list_item	A list of items and their values or expressions
env_ch	Environment in which to save list (should not be defined by user)

Details

The functions to add/modify events/inputs use lists. Whenever several inputs/events are added or modified, it's recommended to group them within one function, as it reduces the computation cost. So rather than use two modify_item with a list of one element, it's better to group them into a single modify_item with a list of two elements.

Examples

## Not run: 
modify_item(list(cost.idfs = 500, cost.tx = cost.tx + 4000))

## End(Not run)
