Small utilities for ragged objects

Description

Small utilities for ragged objects. Modify the elements of raggedCoef objects, extract them as a vector.

Usage

rag_modify(rag, v)
ragged2vec(x)

Arguments

rag	the raggedCoef object to be modified.
v	vector of values to replace the old ones.
x	a raggedCoef object.

Details

An error will occur if the length of v is not equal to sum(rag@p).

rag_modify is, in a sense, the inverse of ragged2vec.

Value

for rag_modify, a raggedCoef object of the same order as rag but with coefficients replaced by the new values.

for ragged2vec, a numeric vector.

Examples

rag1 <- new("raggedCoef", list(1, 2:3, 4:6))
a1 <- (1:6)^2
rag1a <- rag_modify(rag1, a1)

rag2 <- new("raggedCoef", list(1, numeric(0), 4:6)) # a zero-length ccomponent
a2 <- (1:4)^2
rag2a <- rag_modify(rag2, a2)
