appDependencies: Detect Application Dependencies

Description

Recursively detect all package dependencies for an application. This function parses all .R files in the applicaition 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 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.

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.
