This is particularly useful for binary variables that have been encoded with e.g. Yes and No as options. Variable labels are retained, which may or may not make sense, depending on the variable

Usage

  data,
  vars,
  true = "Yes",
  replace = TRUE,
  append = "_logical"
)

Arguments

data	dataframe
vars	character string of variables to convert
true	value which should become TRUE
replace	Replace the indicated variables
append	text to append to new variables (when replace = TRUE)

Value

data with modified variables, potentially with additional variables (if replace = TRUE)

Examples

data(mtcars)
convert_to_logical(mtcars, "am", 1)
convert_to_logical(mtcars, c("am", "vs"), 1)
convert_to_logical(mtcars, c("am", "vs"), 1, FALSE)
convert_to_logical(mtcars, c("am", "vs"), 1, FALSE, "_lgl")
