This function 'draws' a context tree as a text.
Usage
draw(ct, control = draw_control(), ...)Arguments
- ct
a context tree.
- control
a list of low level control parameters of the text representation. See details and
draw_control().- ...
additional arguments for draw.
Details
The function uses basic "ascii art" to represent the context tree. Characters
used to represent the structure of the tree, e.g. branches, can be modified
using draw_control().
In addition to the structure of the context tree, draw can represent
information attached to the node (contexts and partial contexts). This is
controlled by additional parameters depending on the type of the context
tree.
Examples
dts <- sample(c(0, 1), 100, replace = TRUE)
ctree <- ctx_tree(dts, min_size = 10, max_depth = 2)
draw(ctree)
#> *
#> +-- 0
#> | +-- 0
#> | '-- 1
#> '-- 1
#> +-- 0
#> '-- 1
dts_c <- sample(c("A", "B", "CD"), 100, replace = TRUE)
ctree_c <- ctx_tree(dts_c, min_size = 10, max_depth = 2)
draw(ctree_c, draw_control(root = "x"))
#> x
#> +-- A
#> | +-- B
#> | '-- CD
#> '-- B
#> | +-- A
#> | '-- B
#> '-- CD
#> +-- A
#> '-- CD
