In xfun: Supporting Functions for Packages Maintained by 'Yihui Xie'

Turn the output of str() into a tree diagram

Description

The super useful function str() uses ⁠..⁠ to indicate the level of sub-elements of an object, which may be difficult to read. This function uses vertical pipes to connect all sub-elements on the same level, so it is clearer which elements belong to the same parent element in an object with a nested structure (such as a nested list).

Usage

tree(...)

Arguments

...	Arguments to be passed to str() (note that the comp.str is hardcoded inside this function, and it is the only argument that you cannot customize).

Value

A character string as a raw_string().

Examples

fit = lsfit(1:9, 1:9)
str(fit)
xfun::tree(fit)

fit = lm(dist ~ speed, data = cars)
str(fit)
xfun::tree(fit)

# some trivial examples
xfun::tree(1:10)
xfun::tree(iris)
