fapply {far}

Apply functions over a fdata object

Description

fapply returns a fdata object of the same length as data. Each element of which is the result of applying FUN to the corresponding element of data.

Usage

fapply(data, FUN, row.names, ...)

Arguments

data

A fdata object

FUN

the function to be applied. In the case of functions like +, %*%, etc., the function name must be quoted.

row.names

a vector giving the names describing the results of FUN

...
