Examples

x <- make_safeframe(cars,
  mph = "speed",
  distance = "dist"
)
x

## the below would issue an error
## note: tryCatch is only used to avoid a genuine error in the example
tryCatch(validate_types(x), error = paste)

## to allow other types, e.g. gender to be integer, character or factor
validate_types(x, mph = "numeric", distance = c(
  "integer",
  "character", "numeric"
))
