SeasonDistance: Similarity measure based on seasonality of annual maxima

In floodnetProject16/floodnetRfa: FloodNet Regional Frequency Analysis

Description

Return the distance matrix between stations based on the seasonality of the annual maximum events. Optionally, a target can be passed to extract only the pooling group from a list of stations.

Usage

SeasonDistance(x, form = date ~ site, target = NULL, ...)

SeasonDistanceData(db, sites, ...)

Arguments

x	Hydrometric data.
form	Formula of the form date~site, that point to the columns with date and site ID.
target	Sites for which distance is returned.
...	Other parameters passed to DistSeason.
db	Path of the HYDAT database,
sites	List of sites in HYDAT.

Examples

## Extract similarity measure from multiple site
## with respect to target station 01AF009
h <- SeasonDistance(DemoData('region'))
print(h[1:3,1:3])
print(h[2,])

## Not run: 

## Path to HYDAT
# DB_HYDAT = ".../hydat.sqlite3"

## Compute the distance using HYDAT directly
SeasonDistanceData(DB_HYDAT, names(h), target = '01AF009')


## End(Not run)
