ui-questions

User interface - Questions

Description

These functions are used to interact with the user by posing a simple yes or no question. For details on the other ui_*() functions, see the ui help page.

Usage

ui_yeah(
  x,
  yes = c("Yes", "Definitely", "For sure", "Yup", "Yeah", "I agree", "Absolutely"),
  no = c("No way", "Not now", "Negative", "No", "Nope", "Absolutely not"),
  n_yes = 1,
  n_no = 2,
  shuffle = TRUE,
  .envir = parent.frame()
)

ui_nope(
  x,
  yes = c("Yes", "Definitely", "For sure", "Yup", "Yeah", "I agree", "Absolutely"),
  no = c("No way", "Not now", "Negative", "No", "Nope", "Absolutely not"),
  n_yes = 1,
  n_no = 2,
  shuffle = TRUE,
  .envir = parent.frame()
)

Arguments

`x`	A character vector. For block styles, conditions, and questions, each element of the vector becomes a line, and the result is processed by `glue::glue()`. For inline styles, each element of the vector becomes an entry in a comma separated list.
`yes`	A character vector of "yes" strings, which are randomly sampled to populate the menu.
`no`	A character vector of "no" strings, which are randomly sampled to populate the menu.
`n_yes`	An integer. The number of "yes" strings to include.
`n_no`	An integer. The number of "no" strings to include.
`shuffle`	A logical. Should the order of the menu options be randomly shuffled?
`.envir`	Used to ensure that `glue::glue()` gets the correct environment. For expert use only.

Value

A logical. ui_yeah() returns TRUE when the user selects a "yes" option and FALSE otherwise, i.e. when user selects a "no" option or refuses to make a selection (cancels). ui_nope() is the logical opposite of ui_yeah().

Examples

## Not run: 
ui_yeah("Do you like R?")
ui_nope("Have you tried turning it off and on again?", n_yes = 1, n_no = 1)
ui_yeah("Are you sure its plugged in?", yes = "Yes", no = "No", shuffle = FALSE)

## End(Not run)
