node

a ctx_node object as returned by find_sequence()

Examples

dts <- c(0, 1, 1, 1, 0, 0, 1, 0, 1, 0)
dts_ctree <- ctx_tree(dts, min_size = 1, max_depth = 3)
draw(dts_ctree)

## 0, 0 is a context but 1, 0 is not
is_context(find_sequence(dts_ctree, c(0, 0)))
#> [1] TRUE
is_context(find_sequence(dts_ctree, c(1, 0)))
#> [1] FALSE
