In fdnonpar: Methods for Multivariate or Functional Data

Description

Applies a function to the curves function values (y-values) in an fdsample object, for each argument value (x-value).

Usage

apply.fdsample(x, fun = mean, ..., fopt = list())

Arguments

x	object of type fdsample
fun	the function to apply, defaults to the mean
...	optional, (plot) options for updating options element of the result
fopt	list of options to fun

Details

The function fun should return a single number or a vector of fixed length. This is not checked.

Examples

data(exampledata)
# look at data set fuda
str(fuda)
# apply the summary function contained in fuda$options
str(apply.fdsample(fuda))
# apply the median
str(apply.fdsample(fuda, "median"))
# apply median and change axis label
str(apply.fdsample(fuda, median, xlab = "median of y-values"))
# another way to get the median and change axis label
str(apply.fdsample(fuda, quantile, list(prob = 0.5), xlab = "50% quantile of y-values"))
