generate_shinyinput {DSAIDE}

A helper function that takes a model and generates shiny UI elements

Description

This function generates shiny UI inputs for a supplied model. This is a helper function called by the shiny app.

Usage

generate_shinyinput(
  use_mbmodel = FALSE,
  mbmodel = NULL,
  use_doc = FALSE,
  model_file = NULL,
  model_function = NULL,
  otherinputs = NULL,
  packagename = NULL
)

Arguments

use_mbmodel

TRUE/FALSE if mbmodel list should be used to generate UI

mbmodel

a valid mbmodel object

use_doc

TRUE/FALSE if doc of a model file should be parsed to make UI

model_file

name/path to function file for parsing doc

model_function

name of function who's formals are parsed to make UI

otherinputs

a text string that specifies a list of other shiny inputs to include in the UI

packagename

name of package using this function

Details

This function is called by the Shiny app to produce the Shiny input UI elements. It produces UI by 3 different ways. 1. If use_mbmodel is TRUE, an mbmodel list structure, which needs to be provided, is used 2. If use_mbmodel is FALSE and use_doc is TRUE, the documentation header of the function is used. For that approach, model_file needs to contain the name/path to the R script for the function The doc needs to have a specific format for this. 3. If both use_mbmodel and use_doc are FALSE, the function formals are parsed and used as UI. For that approach, model_function needs to specify the name of the model model_function is assumed to be the name of a function. The formals of the function will be parsed to create UI elements. Non-numeric arguments of functions are removed and need to be included in the otherinputs argument.

Value

A renderUI object that can be added to the shiny output object for display in a Shiny UI
