appDependencies: Detect Application Dependencies

Description

Recursively detect all package dependencies for an application. This function parses all .R files in the application directory to determine what packages the application depends on; and for each of those packages what other packages they depend on.

Usage

appDependencies(appDir = getwd(), appFiles = NULL)

Arguments

appDir

Directory containing application. Defaults to current working directory.

appFiles

The files and directories to bundle and deploy (only if upload = TRUE). Can be NULL, in which case all the files in the directory containing the application are bundled. Takes precedence over appFileManifest if both are supplied.

Value

Returns a data frame listing the package dependencies detected for the application:

`package`	Name of package
`version`	Version of package

Details

Dependencies are determined by parsing application source code and looking for calls to library, require, ::, and :::.

Recursive dependencies are detected by examining the Depends, Imports, and LinkingTo fields of the packages immediately dependend on by the application.

Examples

Run this code

# NOT RUN {
# dependencies for the app in the current working dir
appDependencies()

# dependencies for an app in another directory
appDependencies("~/projects/shiny/app1")
# }
