Ah, it seems that the problem is that the default is already FALSE: ``` #' @param unify_schemas logical: should all data fragments (files, `Dataset`s) #' be scanned in order to create a unified schema from them? If `FALSE`, only #' the first fragment will be inspected for its schema. Use this fast path #' when you know and trust that all fragments have an identical schema. #' The default is `FALSE` when creating a dataset from a directory path/URI or #' vector of file paths/URIs (because there may be many files and scanning may #' be slow) but `TRUE` when `sources` is a list of `Dataset`s (because there #' should be few `Dataset`s in the list and their `Schema`s are already in #' memory). ``` > The default is `FALSE` when creating a dataset from a directory path/URI or #' vector of file paths/URIs (because there may be many files and scanning may #' be slow) -- This is an automated message from the Apache Git Service.
