-#' @template r5r_core

-#' @template fare_structure
-#' @template verbose
-#' @param percentiles An integer vector (max length of 5). Specifies the

-#'   time window. Please note that this parameter is applied to the travel time
-#'   estimates only (e.g. if the 25th percentile is specified, and the output

-\arguments{
-\item{r5r_core}{An object to connect with the R5 routing engine, created with
-\code{\link[=setup_r5]{setup_r5()}}.}
-
-\item{origins, destinations}{Either a \verb{POINT sf} object with WGS84 CRS, or a
-\code{data.frame} containing the columns \code{id}, \code{lon} and \code{lat}.}
-
-\item{mode}{A character vector. The transport modes allowed for access,
-transfer and vehicle legs of the trips. Defaults to \code{WALK}. Please see
-details for other options.}
-
-\item{mode_egress}{A character vector. The transport mode used after egress
-from the last public transport. It can be either \code{WALK}, \code{BICYCLE} or
-\code{CAR}. Defaults to \code{WALK}. Ignored when public transport is not used.}
-
-\item{departure_datetime}{A POSIXct object. Please note that the departure
-time only influences public transport legs. When working with public
-transport networks, please check the \code{calendar.txt} within your GTFS feeds
-for valid dates. Please see details for further information on how
-datetimes are parsed.}
-
-\item{time_window}{An integer. The time window in minutes for which \code{r5r}
-will calculate multiple travel time matrices departing each minute.
-Defaults to 10 minutes. By default, the function returns the result based
-on median travel times, but the user can set the \code{percentiles} parameter to
-extract more results. Please read the time window vignette for more details
-on its usage \code{vignette("time_window", package = "r5r")}}
-
-\item{percentiles}{An integer vector (max length of 5). Specifies the
-percentile to use when returning travel time estimates within the given
-time window. Please note that this parameter is applied to the travel time
-estimates only (e.g. if the 25th percentile is specified, and the output
-between A and B is 15 minutes and 10 dollars, 25\% of all trips cheaper
-than 10 dollars taken between these points are shorter than 15 minutes).
-Defaults to 50, returning the median travel time. If a vector with length
-bigger than 1 is passed, the output contains an additional column that
-specifies the percentile of each travel time and monetary cost
-combination. Due to upstream restrictions, only 5 percentiles can be
-specified at a time. For more details, please see R5 documentation at
-\url{https://docs.conveyal.com/analysis/methodology#accounting-for-variability}.}
-
-\item{max_walk_time}{An integer. The maximum walking time (in minutes) to
-access and egress the transit network, to make transfers within the network
-or to complete walk-only trips. Defaults to no restrictions (numeric value
-of \code{Inf}), as long as \code{max_trip_duration} is respected. When routing
-transit trips, the max time is considered separately for each leg (e.g. if
-you set \code{max_walk_time} to 15, you could get trips with an up to 15 minutes
-walk leg to reach transit and another up to 15 minutes walk leg to reach
-the destination after leaving transit. In walk-only trips, whenever
-\code{max_walk_time} differs from \code{max_trip_duration}, the lowest value is
-considered.}
-
-\item{max_bike_time}{An integer. The maximum cycling time (in minutes) to
-access and egress the transit network, to make transfers within the network
-or to complete bicycle-only trips. Defaults to no restrictions (numeric
-value of \code{Inf}), as long as \code{max_trip_duration} is respected. When routing
-transit trips, the max time is considered separately for each leg (e.g. if
-you set \code{max_bike_time} to 15, you could get trips with an up to 15 minutes
-cycle leg to reach transit and another up to 15 minutes cycle leg to reach
-the destination after leaving transit. In bicycle-only trips, whenever
-\code{max_bike_time} differs from \code{max_trip_duration}, the lowest value is
-considered.}
-
-\item{max_car_time}{An integer. The maximum driving time (in minutes) to
-access and egress the transit network. Defaults to no restrictions, as long
-as \code{max_trip_duration} is respected. The max time is considered separately
-for each leg (e.g. if you set \code{max_car_time} to 15 minutes, you could
-potentially drive up to 15 minutes to reach transit, and up to \emph{another} 15
-minutes to reach the destination after leaving transit). Defaults to \code{Inf},
-no limit.}
-
-\item{max_trip_duration}{An integer. The maximum trip duration in minutes.
-Defaults to 120 minutes (2 hours).}
-
-\item{fare_structure}{A fare structure object, following the convention
-set in \code{\link[=setup_fare_structure]{setup_fare_structure()}}. This object describes how transit fares
-should be calculated. Please see the fare structure vignette to
-understand how this object is structured:
-\code{vignette("fare_structure", package = "r5r")}.}
-
-\item{walk_speed}{A numeric. Average walk speed in km/h. Defaults to 3.6
-km/h.}
-
-\item{bike_speed}{A numeric. Average cycling speed in km/h. Defaults to 12
-km/h.}
-
-\item{max_rides}{An integer. The maximum number of public transport rides
-allowed in the same trip. Defaults to 3.}
-
-\item{max_lts}{An integer between 1 and 4. The maximum level of traffic
-stress that cyclists will tolerate. A value of 1 means cyclists will only
-travel through the quietest streets, while a value of 4 indicates cyclists
-can travel through any road. Defaults to 2. Please see details for more
-information.}
-
-\item{n_threads}{An integer. The number of threads to use when running the
-router in parallel. Defaults to use all available threads (Inf).}
-
-\item{verbose}{A logical. Whether to show \code{R5} informative messages when
-running the function. Defaults to \code{FALSE} (please note that in such case
-\code{R5} error messages are still shown). Setting \code{verbose} to \code{TRUE} shows
-detailed output, which can be useful for debugging issues not caught by
-\code{r5r}.}
-
-\item{progress}{A logical. Whether to show a progress counter when running
-the router. Defaults to \code{FALSE}. Only works when \code{verbose} is set to
-\code{FALSE}, so the progress counter does not interfere with \code{R5}'s output
-messages. Setting \code{progress} to \code{TRUE} may impose a small penalty for
-computation efficiency, because the progress counter must be synchronized
-among all active threads.}
-
-\item{output_dir}{Either \code{NULL} or a path to an existing directory. When not
-\code{NULL} (the default), the function will write one \code{.csv} file with the
-results for each origin in the specified directory. In such case, the
-function returns the path specified in this parameter. This parameter is
-particularly useful when running on memory-constrained settings because
-writing the results directly to disk prevents \code{r5r} from loading them to
-RAM memory.}
