plot the tree as a network graph

Usage

# S4 method for class 'atctree'
plot(
  x,
  circle = NULL,
  ATC_text = NULL,
  leaf_label = NULL,
  stem_label = NULL,
  text_size = 10,
  text_angle = 45,
  width = 500,
  height = 500,
  hover_msg = T
)

Arguments

x: an object of class atctree
circle: whether or not to arrange graph over a circle
ATC_text: whether or not to label with ATC textual info
leaf_label: whether or not leaf nodes will be labelled
stem_label: whether or not stem nodes will be labelled
text_size: annotation text size
text_angle: annotation text angle
width: graph width
height: graph height
hover_msg: whether to remind the user that they can hover over nodes

Value

No return value, called for side effects

Details

Each node is labelled with its ATC code, and by hovering the cursor over any node the ATC desciption is displayed. The ATC tree can be displayed as a network in layers or on a circle (with radii corresponding to ATC level). It is evident that a plot the full ATC tree is too cluttered. Some subsetting (link), pruning (link) or cutting (link) of the tree is likely to help visualisation.

Examples

# create an ATC tree and plot the whole thing:
h <- atctree(schema="full")
# you could plot this with plot(h) but it takes a while 
# large network so not easy to read

# take cutting above node B ; plot all its descendants:
plot(cutting(h,"B"))
#> Remember you can hover over nodes to see text


# plot siblings of node A03
plot(h["A03",0])
#> Remember you can hover over nodes to see text


# plot node B down to its grandchildren:
plot(h["B",-2])
#> Remember you can hover over nodes to see text

# or use a circular layout
plot(h["B",-2], circle=TRUE, stem_label=TRUE)
#> Remember you can hover over nodes to see text
