code_section: Pascal script to check registry for R

In RInno: An Installation Framework for Shiny Apps

Description

Modern Delphi-like Pascal adds a lot of customization possibilities to the installer. For examples, please visit Pascal Scripting Introduction.

Usage

code_section(iss, R_version = paste0(">=", R.version$major, ".",
  R.version$minor))

Arguments

iss	Character vector which cumulatively becomes an Inno Setup Script (ISS).
R_version	R version to use. Supports inequalities. Defaults to: paste0(">=", R.version$major, '.', R.version$minor).

Details

This script checks the registry for R, so that R will only be installed if necessary.

Value

Chainable character vector, which can be used as the text argument of writeLines to generate an ISS.
