R Documentation

Assign variables to the system environment.

Description

Create a system environment variable with the use of variables. While 'var.name = "testname"; var.value = 7' and 'Sys.setenv(var.name = var.value)' will create 'var.name = 7' in the system environment, 'DIZtools::setenv2(key = var.name, val = var.value)' will create 'testname = 7' in the system environment.

Usage

setenv2(key, val)

Arguments

`key`	A character (!) string. The name of the assigned variable
`val`	An object. The object that will be assigned to 'key'.

Value

No return value, called for side effects (see description).

Examples

  var.name = "testname"
  var.value = 7

  Sys.setenv(var.name = var.value)

  Sys.getenv("testname")
  #> [1] ""
  Sys.getenv("var.name")
  #> [1] "7"

  Sys.unsetenv("var.name")
  Sys.unsetenv("testname")

  setenv2(key = var.name, val = var.value)
  Sys.getenv("testname")
  #> [1] "7"
