Compute profiles limits

Description

Function to compute prototype profile and confidence bands for a set of profiles (Phase I)

Usage

climProfiles(
  profiles,
  x = 1:nrow(profiles),
  smoothprof = FALSE,
  smoothlim = FALSE,
  alpha = 0.01
)

Arguments

`profiles`	Matrix with profiles in columns
`x`	Vector for the independent variable
`smoothprof`	regularize profiles? [FALSE]
`smoothlim`	regularize confidence bands? [FALSE]
`alpha`	limit for control limits [0.01]

Value

a matrix with three profiles: prototype and confidence bands
