Set meta columns on DAG

# S4 method for ontology_DAG
mcols(x, ...) <- value

Arguments

x: An ontology_DAG object.
...: Other argument. For mcols(), it can be a vector of column names in the meta data frame.
value: A data frame or a matrix where rows should correspond to terms in x@terms.

Examples

parents  = c("a", "a", "b", "b", "c", "d")
children = c("b", "c", "c", "d", "e", "f")
dag = create_ontology_DAG(parents, children)
mcols(dag) = data.frame(id = letters[1:6], v = 1:6)
mcols(dag)
#>   id v
#> 1  a 1
#> 2  b 2
#> 3  c 3
#> 4  d 4
#> 5  e 5
#> 6  f 6
mcols(dag, "id")
#>   id v
#> 1  a 1
#> 2  b 2
#> 3  c 3
#> 4  d 4
#> 5  e 5
#> 6  f 6
dag
#> An ontology_DAG object:
#>   Source: Ontology 
#>   6 terms / 6 relations
#>   Root: a 
#>   Terms: a, b, c, d, ...
#>   Max depth: 3 
#>   Aspect ratio: 0.67:1 (based on the longest distance to root)
#>                 0.68:1 (based on the shortest distance to root)
#> 
#> With the following columns in the metadata data frame:
#>   id, v
