conversions: IndexedRelation conversions

In LTLA/IndexedRelations: Representing Indexed Relationships Between Features

Description

Convert an IndexedRelations object to and from different Bioconductor classes.

Details

A number of coerce methods are available to convert to/from an IndexedRelations object:

• as(from, "IndexedRelations") for a Pairs x will return an IndexedRelations object where the first vector in from becomes the first partner in the output.

• as(from, "IndexedRelations") for a DataFrame x will return an IndexedRelations object where the first column in from becomes the first partner in the output.

• as(from, "DataFrame") for an IndexedRelations x will return a DataFrame object where the first column is the first partner in From.

In addition, makePairsFromIndexedRelations(x) will create a Pairs instance from an IndexedRelations x. This requires that x only has two partners in each relationship, otherwise an error is thrown.

Examples

p <- Pairs(1:10, Rle(1L, 10), score=rnorm(10), names=letters[1:10])

ir <- as(p, "IndexedRelations")
ir

back <- makePairsFromIndexedRelations(ir)
back

df <- as(ir, "DataFrame")
df

as(df, "IndexedRelations")
