| Title: | Scan Statistics for Railway Network |
| Version: | 0.1.0 |
| Date: | 2020-06-14 |
| Description: | Implement the algorithm provided in scan for estimating the transmission route on railway network using passenger volume. It is a generalization of the scan statistic approach for railway network to identify the hot railway route for transmitting infectious diseases. |

Convert station data to adjacency matrix
Description
Convert station data to adjacency matrix
Usage
make_adjacency_matrix(stations, depart, arrive)
Arguments
stations |
data.frame which set of stopping points recorded in order of stopping. |
depart |
Column name of a stop. |
arrive |
Give the name of the column indicating the next stop at the target stop. |
Examples
make_adjacency_matrix(jreast_jt, st_code, next_st_code)
Convert passenger and station data to origin-destination matrix
Description
Convert passenger and station data to origin-destination matrix
Usage
make_passenger_matrix(passenger, stations, depart, arrive, location, value)
Arguments
passenger |
passenger data |
stations |
data.frame which set of stopping points recorded in order of stopping. |
depart |
Column name of a stop. |
arrive |
Give the name of the column indicating the next stop at the target stop. |
location |
Name of the variable to use for the join, indicating its location. |
value |
origin-destination value name |
Examples
jreast_jt_od %>%
make_passenger_matrix(jreast_jt,
departure_st_code,
arrive_st_code,
st_code,
volume)
Summaries a passenger volume
Description
Summaries a passenger volume
Usage
make_passenger_od(
passenger,
stations,
depart,
arrive,
location,
value,
.all = FALSE
)
Arguments
passenger |
passenger data |
stations |
data.frame which set of stopping points recorded in order of stopping. |
depart |
Column name of a stop. |
arrive |
Give the name of the column indicating the next stop at the target stop. |
location |
Name of the variable to use for the join, indicating its location. |
value |
origin-destination value name |
.all |
Make a join that contains rows of two datasets. The default value is FALSE. |
Examples
jreast_jt_od %>%
make_passenger_od(jreast_jt,
depart = departure_st_code,
arrive_st_code,
location = st_code,
value = volume) %>%
dplyr::left_join(jreast_jt %>%
dplyr::select(arrive_st_code = st_code,
next_st_name = st_name),
by = "arrive_st_code")
Create network window zones
Description
Create network window zones
Usage
network_window(adjacency_matrix, dist_matrix, type, cluster_max)
Arguments
adjacency_matrix |
A boolean matrix, with element (i,j) set to TRUE if location j is adjacent to location i. |
dist_matrix |
Distance matrix |
type |
Currently, "connected_B" only. |
cluster_max |
Maximum cluster size. Zone If this value is reached, the area will not be expanded any further. It's a good idea to keep it to the number of stops on the line you're dealing with. |

Description
Create transit table
Usage
transit_table(stations, ..., reverse = FALSE)
Arguments
stations |
data.frame which set of stopping points recorded in order of stopping. |
... |
Arguments passed on to
|
reverse |
Option to swap the order of the stopping points. |
Examples
# The next stop is stored in the variable of column next_.
jreast_jt %>%
transit_table()
# Switch between inbound and outbound lines.
jreast_jt %>%
transit_table(reverse = TRUE)
