Dummy-code a multiple response vector into a binary data frame

Source: R/FUNCTIONS_RECODE.R
dummy_arrange.Rd

Splits a vector of comma-separated multiple response values and returns a binary data frame where each unique response becomes a column, with 1 indicating the response was selected and 0 indicating it was not.

Usage

dummy_arrange(vector)

Arguments

vector

A character or numeric vector where each element contains one or more comma-separated response values (e.g. from a multiple choice question). Single-value responses are also accepted.

Value

A binary data frame with one row per element of vector and one column per unique response value, sorted alphabetically by column name. Values are 1 (selected) or 0 (not selected).

Examples

vector1 <- gsub(" ", "",
  generate_multiple_response_vector(
    responses = c("Agree", "Hi", "All"),
    responded = 1:3, length = 10
  ),

)
vector2 <- gsub(" ", "",
  generate_multiple_response_vector(responses = 1:4, responded = 1:4, length = 10),
  fixed = TRUE
)
vector3 <- sample(1:4, 10, replace = TRUE)
vector4 <- sample(LETTERS[1:3], 10, replace = TRUE)
