create_template(
  path,
  name,

  include_table = TRUE,
  include_code = TRUE,
  install = FALSE,
  logger = NULL
)

Value

No return value, called for side effects

Arguments

path

character. Path to where the app should be created

name

character. Name of the app which will be used as the package name. Must be only characters and numbers and not start with a number.

• component character. Single word descriptor for the component used to name files

• long_component character. Full component name displayed to the user, formatted appropriately

• module character. Single word descriptor for the module used to name files

• long_module character. Full module name displayed to the user, formatted appropriately

• map logical. Whether or not the module interacts with the map

• result logical. Whether or not the module produces results

• rmd logical. Whether or not the module is included in the markdown

• save logical. Whether or not the input values of the model should be saved

• async logical. Whether or not the module will run asynchronously

author
