fncDepth function

Basic function for functional depths

Calculates depth functions.

fncDepth(u, X = NULL, method = "MBD", byrow = NULL, ...)

## S3 method for class 'matrix'
fncDepth(u, X = NULL, method = "MBD", byrow = NULL, ...)

## S3 method for class 'zoo'
fncDepth(u, X = NULL, method = "MBD", byrow = NULL, ...)

Arguments

• u: data
• X: reference set. If null u will be used as reference.
• method: depth method - "MBD" (default), or "FM" (Frainman-Muniz depth)
• byrow: logical or character.
• ...: additional arguments passed to fncDepthFM.

Examples

x <- matrix(rnorm(60), ncol = 20)
fncDepth(x, method = "FM", dep1d = "Mahalanobis")
fncDepth(x, byrow = FALSE)

# zoo and xts
library(xts)
data(sample_matrix)
sample.xts <- as.xts(sample_matrix, descr = "my new xts object")
fncDepth(sample.xts)
