mcgf_rs function

Create mcgf_rs object

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

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.

Returns

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.

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")
