mcgf (version 1.1.1)

mcgf_rs: Create mcgf_rs object

Description

Create mcgf_rs object

Usage

mcgf_rs(data, locations, dists, label, time, longlat = TRUE, origin = 1L)

Value

An S3 object of class mcgf_rs. As it inherits and extends the mcgf and then thedata.frame class, all methods remain valid to the data part of the object. Additional attributes may be assigned and extracted.

Arguments

data

Time series data set in space-wide format.

locations

A matrix of data.frame of 2D points, first column longitude, second column latitude, both in decimal degrees. Required when dists is not supplied.

dists

List of signed distance matrices. Required when locations is not supplied.

label

A vector of regime labels. Its length must be the same as the number rows in data.

time

Optional, a vector of equally spaced time stamps.

longlat

Logical, if TURE locations contains longitudes and latitudes.

origin

Optional; used when longlat is TRUE. An integer index indicating the reference location which well be used as the origin.

Details

An mcgf_rs object extends the S3 classes mcgf and data.frame.

For inputs, data must be in space-wide format where rows correspond to different time stamps and columns refer to spatial locations. Supply either locations or dists. locations is a matrix or data.frame of 2D points with first column x/longitude and second column y/latitude. By default it is treated as a matrix of Earth's coordinates in decimal degrees. Number of rows in locations must be the same as the number of columns of data. dists must be a list of signed distance matrices with names h1, h2, and h. If h is not given, it will be calculated as the Euclidean distance of h1 and h2. time is a vector of equally spaced time stamps. If it is not supplied then data is assumed to be temporally equally spaced. label must be a vector containing regime labels, and its length must be the same as the number of rows in x.

An mcgf_rs object extends the S3 classes mcgf and data.frame, all methods remain valid to the data part of the object.

Examples

data <- cbind(S1 = 1:5, S2 = 4:8, S3 = 5:9)
lon <- c(110, 120, 130)
lat <- c(50, 55, 60)
locations <- cbind(lon, lat)
label <- c(1, 1, 2, 2, 2)
obj <- mcgf_rs(data, locations = locations, label = label)
print(obj, "locations")
print(obj, "label")
