xfun (version 0.48)

tree: 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(...)

Value

A character string as a raw_string().

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).

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)
