Arguments

id

id of module

label

label of button

title

(character) module title

titleTag

(character) HTML tag to put around the title, e.g. "h4" for h4 from htmltools

defaultSource

(character) default source for input "Source", e.g. "ckan", "file", or "url"

ckanFileTypes

(character) file types allowed for import from Pandora ("ckan"). E.g. for `importType = "model"`: c("resources", "zip"); `importType = "zip"`: c("zip"); for `importType = "list"`: c("json")

ignoreWarnings

(logical) TRUE to enable imports in case of warnings

importType

(character) type of import, either "model", "zip" or "list". ImportType == "model" expects a zip file containing a model. The file will be unzipped, the model object extracted, and checked if it is valid for the app. ImportType == "zip" enables the optional parameter 'expectedFileInZip'. The file is validated and the path to the zip file will be returned. ImportType == "list" expects a json file containing a list. The file will be read and checked.

fileExtension

(character) (otional) app specific file extension, e.g. "resources", "bmsc", "bpred", or (app-unspecific) "zip". Only files with this extension are valid for import.

subFolder

(character) (optional) subfolder containing loadable .zip files.

onlySettings

(logical) if TRUE allow only upload of user inputs and user data.

expectedFileInZip

(character) (optional) This parameter is ignored if importType != "zip". File names that must be contained in the zip upload.

options

(list) Extra options for the import module. See importOptions.
