Weave a new LinkMap from a MultiFactor

Generates a new LinkMap object by cross-referencing the elements of a given MultiFactor

Usage

weave(x, .by = NULL, out.format = c("LinkMap", "matrix"))

Arguments

x

a MultiFactor

.by

either a formula or a `character vector“ of length 2 with the names of the desired combination of feature types.

out.format

Character scalar. One of 'LinkMap', 'matrix'.

Value

a LinkMap or sparse Matrix.

Examples

# Generate pair of 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(c("x", "y", "z"), 10, replace = TRUE)
)

# Create MultiFactor
x <- MultiFactor(list(a2b, a2c))

# Weave new b2c LinkMap
weave(x, b ~ c)
#>   b c
#> 1 A x
#> 2 B x
#> 3 C x
#> 4 A y
#> 5 B y
#> 6 C y
#> 7 A z
#> 8 C z
weave(x, b ~ a, out.format = "matrix")
#> 3 x 3 sparse Matrix of class "ngCMatrix"
#>    a
#> b   a b c
#>   A | | |
#>   B | | .
#>   C | | |
