MultiFactor S7 container class

MultiFactor is an S7 class to organize and manage multiple sets of factors, for instance when tracing or converting feature IDs across databases. Methods for MultiFactor aim to follow factor behaviour.

Usage

MultiFactor(x)

Arguments

x

a LinkMap, or named list of LinkMap objects.

Value

a MultiFactor object.

Details

The most straightforward way to construct a MultiFactor object is as a named list of named data.frames. The columns of the data.frames indicate the category of factor in that column.

A MultiFactor object presents itself similar to a data.frame, in the sense that level types can be called as columns and individual data.frame components can be called as rows. MultiFactor inherits from list; Content can be accessed through regular list methods (e.g., [, [[).

Slots

levels

Named list of character vectors. Accessed through levels(x)

map

(sparse) Matrix specifying which elements contain which levels.

Examples

# Generate some random linkage input
a2b <- data.frame(
    a = sample(letters[seq(3)], 10, replace = TRUE),
    b = sample(LETTERS[seq(3)], 10, replace = TRUE)
)
a2c <- data.frame(
    a = sample(letters[seq(3)], 10, replace = TRUE),
    c = sample(LETTERS[seq(3)], 10, replace = TRUE)
)
x <- MultiFactor(list(a2b, a2c))
