create_application {periscope2}

Create a new templated framework application

Description

Creates ready-to-use templated application files using the periscope2 framework. The application can be created either empty (default) or with a sample/documented example application.

Usage

create_application(
  name,
  location,
  sample_app = FALSE,
  left_sidebar = TRUE,
  right_sidebar = FALSE
)

Arguments

name

name for the new application and directory

location

base path for creation of name

sample_app

whether to create a sample shiny application

left_sidebar

whether the left sidebar should be enabled. It can be TRUE/FALSE

right_sidebar

parameter to set the right sidebar. It can be TRUE/FALSE

Value

no return value, creates application folder structure and files

Name

The name directory must not exist in location. If the code detects that this directory exists it will abort the creation process with a warning and will not create an application template.

Use only filesystem-compatible characters in the name (ideally w/o spaces)
