Basic function for functional depths

Source: R/functional_depths.R

Calculates depth functions.

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

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

# S3 method for 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
